Iodine - Wikipedi

  • Residues of iodine must be treated with sodium thiosulphate solution (→ reduction to iodide). Before disposal in the wastewater, the pH value of the reaction mixture must be neutralized with sodium hydrogen carbonate. Iodine must never be brought into contact with ammonia, otherwise explosive iodine nitrogen can be formed
  • Elemental iodine is hardly soluble in pure water. However, if there are already dissolved iodide ions, the iodine dissolves with the formation of polyiodide ions: + - ↽ - - ⇀ - + ↽ - - ⇀ - Therefore, iodine is dissolved together with potassium iodide
  • At normal temperature, iodine is a solid substance in the form of gray, shiny crystals. When heated, they immediately turn into a gaseous state and solidify again when cooled. The vapors are intensely purple in color and have a pungent odor. Iodine is hardly soluble in water; it dissolves better in organic solvents. Iodine is somewhat less reactive than chlorine and bromine, otherwise it is very similar to these in terms of chemical properties
  • Iodine only dissolves in water at a concentration of 0.3 grams per liter. The light brown, aqueous solution is called iodine water. When exposed to light, an iodine solution breaks down into hydrogen iodide and oxygen. Such a solution is acidic. Iodine solutions must be stored in brown bottles. Iodine dissolves much better in aqueous iodide solutions, forming a deep brown solution
  • Iodine potassium iodide solution. Iodine-potassium iodide solution (or in laboratory jargon iodine-iodine potassium) is a solution of iodine in water. Elemental iodine is hardly soluble in water. However, if there are already dissolved iodide ions, the iodine dissolves with the formation of polyiodide ions: 2 I 2 + I - → I 3− + I 2 → I 5−. Therefore, potassium iodide is added
  • Residues of iodine must be treated with sodium thiosulphate solution (→ reduction to iodide). Before disposal in the wastewater, the pH value of the reaction mixture must be neutralized with sodium hydrogen carbonate. Iodine must never be brought into contact with ammonia, otherwise explosive iodine nitrogen can be formed. Analyti
  • The iodine solution is actually an iodine / potassium iodide solution. The iodine formed dissolves in excess of potassium iodide. Therefore, potassium iodide is added in excess. The iodine concentration is therefore determined by the concentration of the iodate solution. According to the equation IO 3- + 5 I- + 6 H + → 3 I 2 + 3 H 2

Chemicals: Iodine potassium iodide solution (0.5%), starch, water, ice Procedure: A starch solution is produced by boiling the starch in water (w = 1%). The solution is cooled to room temperature. The two test tubes are filled halfway with the starch solution. Drops of the iodine-potassium iodide solution are added to both test tubes until the. An iodine-potassium iodide solution forms the classic basis for the detection of starch. This is stored under the exclusion of light and added quickly. 3 properties. Positive strength detection: violet coloration of the preparation. Negative strength detection: no color change. Reversible by heat. Light-sensitive reagent. Storage under exclusion of light. Careful handling in the laboratory. Iodine is bound to carrier substances to reduce germs (disinfection) and to support wound healing. Iodine is effective against a wide variety of pathogens such as bacteria, viruses and fungi PVP-Jod AL solution must not be used at the same time or shortly afterwards with mercury-containing wound treatment agents or disinfectants, as iodine and mercury may form a substance that can damage the skin. Patients who are treated with lithium preparations should use PVP-Jod AL regularly, especially on large areas. Iodine is produced, initially the ascorbic acid acts as a reducing agent, figure not included in this sample. but when the ascorbic acid has completely reacted to dehydroascorbic acid, the iodine, which is no longer reduced to iodide ions, forms a characteristic deep blue color together with the starch in the solution

Periodic table: iodine - SEILNACH

I. is only very slightly soluble in water (0.022 g in 100 g H 2 O) with a pale brownish-yellow color; in potassium iodide solution, on the other hand, it is very easily soluble with a dark brown color with the formation of potassium triiodide KI 3. Characteristic of I. is its ability to also form cationic compounds in the +1 and +3 oxidation states. So is iodine (I) perchlorate by reaction of I. with. Iodine dissolves much better in potassium iodide solutions, which is why the potassium iodide should always be dissolved first. The procedure is to first dissolve the potassium iodide in a little water and then add the iodine and stir this mixture until all of the iodine has dissolved. The better solution of iodine in potassium iodide solutions is due to the reaction of the. Iodine- Potassium iodide solution is also called Lugol's solution and is a solution of Iodine in water. It is named after the French doctor Jean Guillaume Lugol (1786-1851) who invented it in 1835. [Elementary Iodine is hardly soluble in water, so potassium iodide is added. Iodine is much more soluble in ethanol, but sometimes ethanol is undesirable as a solvent because it is. Investigated reaction with iodine solution. The effect of heat on an iodine-starch solution and the effect of saliva are also tested. Classification1 The experiment can be carried out in qualification phase Q2 on the subject of carbohydrates. Every student should carry out the starch-iodine reaction themselves, as it is important evidence. Free iodine can also be recognized by its violet, typically smelling vapor or by the fact that an alcoholic solution turns brown in the presence of iodine, while a hexane solution turns red-violet. Iodide ions, for example from sodium iodide, can be detected via numerous precipitation reactions

Iodine colors the starch solution deep blue because the amylose is wrapped around an enclosed iodine atomic chain. Every six glucose molecules form a coil with a diameter of 0.6 nm. The I-I distance is 0.31 nm, i.e. only 0.04 nm more than in the I2 molecule (0.27 nm). Biological significance: iodine is stored in the thyroid gland. This is where the iodine-containing thyroid hormones are found. Evidence as bromine and iodine []. Another way to differentiate between bromide and iodide is the addition of chlorine water or (a little) chloramine T with hydrochloric acid, whereby the halide ions are oxidized to the halogen. An organic solvent such as n-hexane is then added and the halogens are dissolved in the organic phase by vigorous shaking (extraction) Iodine dissolves very little in water, but it can attach itself to the iodide ion and form I3 ^ -. This means that these iodide ions will trap some of your iodine. My suggestion would be: Dissolve the iodine in a non-polar solvent such as hexane or heptane, filter it off and maybe repeat the process. You can see from the color when all iodine has been removed. Is that iodine for now? The solution contains high-dose iodine and iodide as follows: Substance: 2%: 5%: Iodine: 2g: 5g: Potassium iodide: 4g: 10g: Purified water: 94g: 85g: An example for a better understanding: A pipette drop of the 5% igen solution contains approx. 2.5 mg elemental iodine and 3.75 mg iodide. That adds up to 6.25 mg of iodine. This total is approximately 50 times the normal recommended dose. If the analysis contains iodide, this is primarily oxidized to iodine under the specified conditions, which dissolves in the organic phase with a purple color. If bromide and iodide are present next to each other, then with slow, dropwise addition of chlorine-water, because of the easier oxidizability (stronger reducing agent), I 2 precipitates first from: I - → Cl 2 I 2 C H Cl 3: violet

All reactions take place in aqueous solution. 1. Iron (III) ions react with iodide ions to form iron (II) ions and iodine. 2. Dichromate ions (Cr2O2 7) react with iodide ions to form iodine and chromium (III) ions. The reaction takes place in the acidic pH range. 3. Sulphurous acid (H2SO3) reacts with iodine to form sulfuric acid and hydrogen iodide. 4. Chromium (III) oxide reacts with nitrate ions. To dissolve the iodine in water as well as possible, shake the test tube vigorously for at least 30 seconds (with the stopper!). Add part of the aqueous iodine solution (only the slightly brownish liquid) to 1 ml of n-heptane and shake gently. Exercises for B1 1. Which forces are responsible for the cohesion of the crystals of iodine, sucrose and sodium chloride.

Iodine is just a very weak semiconductor . Compare the specific electrical conductivity of iodine with that of other substances, in each case at 25 ° C. Iodine: 0.77 * 10 -9 ohm -1 cm -1; Copper (the best metallic conductor): 5.96 * 10 5 ohm -1 cm -1; Silicon (a well-known semiconductor): 2.52 * 10 -6 Ohm -1 cm - Lugol's solution is an iodine-potassium iodide solution or a solution of iodine in water. It is named after the French doctor Jean Guillaume Lugol (1786-1851) who invented it in 1835. The iodine-potassium iodide solution is one of the most important and inexpensive drugs of our time. Area of ​​application Iodine is an indispensable component 13 Iodine-zinc chloride solution Detection of cellulose. Preparation 20 g of anhydrous zinc chloride are dissolved in 10 ml of distilled water and mixed with another solution consisting of 2.1 g of potassium iodide and 0.5 g of iodine in 5 ml of distilled water. After the liquid has been decanted from the sediment into a storage bottle, 2 small iodine crystals are added to the solution. Iodine per drop = 2.4 mg min Carefully made in the UK Health Leads makes Lugol's iodine and iodide solution according to the Dr. Hulda Clark recipe. Lugols contains iodine and iodide. Leaked fluid can usually be removed with vitamin C. This product comes in safe packaging iodide per 1 ml = 66 mg, per drop = 3.6 mg max .; Iodine per 1ml = 44mg, per drop = 2.4 mg min.

For solids: put a few drops of iodine solution directly on the product; Or: Chop up the solid, add a little water, add a little iodine to the solution: the faster a blue / black color appears, the more starch it contains. Background: iodine forms a blue dye with starch. With the same amount of iodine (3-5 drops), the more starch, the faster the dye is formed. Preparation of iodine-potassium iodide solution (Lugol's solution) Basics With Lugol's solution, strength can be proven. Iodine atoms are incorporated into the starch structure, forming a blue color. Devices beaker (200 ml), stir bar made of glass. Chemicals iodine (Xn), potassium iodide, distilled water. Procedure 1 g of iodine and 2 g of potassium iodide are distilled in about 4 ml. Iodine is an indispensable substance that the human body needs. As a rule, we take in enough iodine with our food, which is then used in our thyroid gland for the production of the hormones: thyroxine, triiodothyronine and diiodtyrosine. Illnesses caused by iodine deficiency have been known for centuries and have been treated with iodite or iodate, which one. The equilibrium constants for the present iodine / iodide / triiodide equilibria are determined with the aid of titrations that are carried out on saturated iodine-potassium iodide solutions of various concentrations with a specific sodium thiosulphate solution. It shows, among other things, that the relationship between the concentration of molecules and ions is linear. How detailed. . 1.2 Relevant identified uses of the substance or mixture and uses advised against Identified uses Laboratory chemical for use by experts, not for medical and.

Only after the second contact is the immune system already sensitized to iodine and triggers various symptoms within 12 to 48 hours after contact with iodine. For this reason, iodine allergy is also classified as a type 4 reaction, as the symptoms only appear with a delay. The focus is on the development of eczema. Eczema is a certain type of rash which. You should simply oxidize the iodide to iodine as well, so that it can no longer hold the other iodine in solution. Then everything fails. But not in the basic one, because it disproportionates into iodide and iodate. If the humans and the jinn got together to achieve something like this post, they would not succeed - even if they helped each other. To. Iodine has only one use. Iodine compounds can be made from it.Iodine tincture (a 5 - 10% solution of iodine in ethanol) was used to disinfect wounds. Today organic iodine complexes are used for this. Properties . Sublimation: Iodine sublimates noticeably even at room temperature. Though his. The alcoholic solution of iodine can have a direct effect on the metabolism, which manifests the amplification process dissimilation. In such a disease as atherosclerosis, the drug causes a slight decrease in the concentration of beta-lipoprotein and cholesterol. In addition, it increases lipoproteinaznuyu and fibrinolytic activity of blood serum and. So iodine dissolves these toxins, they enter the bloodstream and violent detoxification reactions can occur (released toxins then circulate in the body). It is precisely these strong reactions to poisons (becoming mobile) that are often mistakenly mistaken for iodine intolerance! In reality they are the sign of an iodine deficiency that has existed for years in the patient.

Mercuchrome-iodine solution must not be used at the same time or shortly afterwards with mercury-containing wound treatments or disinfectants, as iodine and mercury can form a substance that can damage the skin. Patients who are treated with lithium preparations should have regular, especially large-area use of Mercuchrom.

This book is a humble attempt at the information widely available on. After cooling in a water-ice mixture, 10 ml of KI solution are added and then titrated with iodine solution (0.05 mol / l) with the addition of 1 ml of starch solution. Here the thiol group is oxidized to the disulfide, at the same time the I 2 is reduced as long as free SH groups are still present. From the equivalence point, the iodine is no longer consumed, which is reflected in the blue coloration of the. If a solution of the element iodine is dripped into a starch solution, the sample immediately turns deep blue. But how this experiment works exactly has been a mystery so far.

So he created a mixture of 5% iodine and 10% potassium iodide in 85% distilled water. 2 drops (or 1 ml) Lugol's solution contain 5 mg iodine and 7.5 mg iodide. Iodide is the reduced form of iodine that has an additional electron. Iodine is an essential mineral that must be supplied in sufficient quantities every day. The official daily requirement (DGE) for iodine in Germany is 180 to 200µg (NRV: 150µg) to avoid a deficiency. An increased iodine requirement applies to certain diseases, such as hypothyroidism in particular, as well as during pregnancy and breastfeeding (230-260µg). Reasons.

I started with 1 drop of the 5% Lugol's solution (1 drop contains approx. 6 mg iodine): Result: headache, increased dreaming, tiredness, my thyroid reacted for hours on that day with slight displeasure, the body temperature fell and alternately rose significantly. I paused for 48 hours recommended by Lynne Farrow, drank a lot of water, and took the as described. Iodine has the potential to change your life. From my point of view, there are four main factors that make us sick today.

Copper and iodine react in a mass ratio of 1: 2. Calculate the ratio formula of copper iodide. Can someone solve this task and explain it to me? Andreia Yes. Andreia CuI2 is the empirical formula. Felix mk / mi = 1/2; n • M = m and thus: (nk • Mk) / (ni • Mi) = 1/2; ni = 2 • Mk • nk / Mi; Now insert and calculate molar masses and then you know e.g. that ni = 2 • nk, but that was just me now. Treatment with iodine. There are different ways to get iodine. For example in the form of potassium iodide tablets, algae preparations kelp, iodoral, Lugol's solution or iodine tablets with elemental iodine. Before taking iodine, the current iodine status should always be determined. Either in the 24-hour urine collection or after one. Iodine-potassium iodide solution = Lugol's solution is applied to the piece of plant. Purple color = positive, e.g. potato. Cellulose. PZ. Iodine-zinc chloride solution: It reacts and forms a complex with cellulose. Staining of a section with a mixture of 0.1% astra blue + 2% tartaric acid in water. Blue coloring. Blue coloring. Lignin. PZ. Phloroglucine HCl under the LM. Obviously, too much iodine triggers the disease with a corresponding genetic disposition and has a negative effect on its course. The reason for this is that iodine promotes the antigen presentation of the immune system. In addition, iodine increases and activates the cells responsible for the autoimmune processes. The constant increase in the incidence of. The crystals are very difficult to dissolve in water; an addition of potassium iodide, on the other hand, increases the solubility considerably (with the formation of polyiodides). 1 part iodine dissolves in about 9 parts ethanol with a brown to red-brown color. At room temperature, 1 part of iodine also dissolves in approx. 5 parts of diethyl ether, 6 parts of benzene (with a red color), 30 parts of chloroform (with a beautiful purple color).

Iodine solution (e.g. Betaisodona, diluted 1:20), snap-cap glasses, plastic funnels, filter paper: Procedure: One to two spatula spoons of soup powder are extracted with approx. 10-15 ml of water by vigorous shaking in the glass. The iodine solution is slowly added dropwise to the filtrate. After adding a few drops, swirl the glass to distribute the iodine throughout the solution. In the case of povidone-iodine, a significant excess of the substance is typical. Since the substance's loss on drying can increase rapidly and the substance is not particularly stable, an excess content of 10% is tolerated during processing and even used for the NRF regulations. With this excess salary, the rapid reduction in salary is quasi-temporarily compensated. Basic rules for.

CAS number: 12298-68-9. EC number: 235-567- iodine An underestimated trace element Everyone knows iodine and most people know that iodine is important for the thyroid and metabolism. Goiter (goiter) is one of the clearest signs of iodine deficiency. However, there are more signals that indicate a possible iodine deficiency. According to the World Health Organization, 1 in 3 people have insufficient iodine.

The solution of a halogen acid is obtained by adding sulfuric acid to the solution of the barium halogenate, with the poorly soluble BaSO 4 precipitating. Ba (XO 3) 2 + 2 H 2 SO 4 -> BaSO 4 + 2HXO 3. All three halogen acids are strong acids. Both the acids and the halogenates are strong oxidizing agents. Mixtures of chlorates with easily oxidizable substances are explosive. The iodine test (iodine-starch reaction) is a chemical method for the detection of starch with the help of an iodine-containing solution. In most cases, an iodine-potassium iodide solution (Lugol's solution) is used, which is dripped onto or with a solid sample The result is iodine starch, which - depending on the concentration of the iodine solution used - a deep blue. After treatment with iodine, you can hardly tell whether the wound is still getting infected because the color hides the wound. Reddening or pus can no longer be seen.
