Why does ki dissolve in water




















Loading DoubtNut Solution for you. Solution : Iodine is covalent in nature and therefore, it does not dissolve in water which is polar. Therefore, it becomes soluble in water.

The chemical formula for potassium iodate is KIO 3. It can be prepared by reacting potassium base with iodic acid. As for potassium , there's nothing to worry about. A tablet of potassium iodide contains less than one-tenth the potassium you'd get from a banana PDF.

While acute toxicity is unlikely, chronically elevated levels of iodine can be dangerous. They can cause goiter and inhibit thyroid functioning. Most iodide salts are soluble in water , but often less so than the related chlorides and bromides. Iodide , being large, is less hydrophilic compared to the smaller anions. One consequence of this is that sodium iodide is highly soluble in acetone, whereas sodium chloride is not.

Why is KI highly soluble in water? The I2 molecules in iodine are not very soluble in water because they are not alike. But KI solution contains I- ions which combine with the I2 molecules to form I3- ions because these are charged they dissolve in the water which is a polar solvent.

Dissolve 5 g of potassium iodide in 10 ml water. Mix the two solutions and add water to make ml. Dissolve 2 g in 10 ml water. To 10 ml of this solution add 90 ml of water and 20 g of sodium bisulfite. The formation of a yellow precipitate represents a positive test for iodide. Answers and Replies There are no two products, there is no reaction at all. The only "product" is a solution containing four different ions.

KI potassium iodide is a salt of stable not radioactive iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury. The thyroid gland is the part of the body that is most sensitive to radioactive iodine. Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt.

Potassium iodide KI is prepared by reacting iodine with a hot solution of potassium hydroxide. It is mainly used in the form of a saturated solution, g of potassium iodide to ml of water. The solution is usually added to water, fruit juice or milk before drinking. As an alternative , people may want to purchase Lugol's Solution, which is a combination of pure iodine , Potassium iodide and water.

One site that sells it is jcrows. One milliliter of Lugol's solution contain mg of iodine an iodide which is slightly more than the mg of KI recommended for adults. Standard iodine 0. Dilute to 1 L and standardize against sodium arsenite, primary standard grade.

Flammability of the Product: Non- flammable. Flammable Limits: Not applicable. This medication is known as an expectorant. Potassium iodide is also used along with antithyroid medicines to prepare the thyroid gland for surgical removal, to treat certain overactive thyroid conditions hyperthyroidism , and to protect the thyroid in a radiation exposure emergency.

It turns yellow when in air. This is because it reacts with oxygen and carbon dioxide to make iodine and potassium carbonate.
