The concentration of the potassium iodide solution should be adjusted so that it gives a light brown solution on addition of chlorine water. If the reagents are too concentrated, a black precipitate of iodine often results instead of a brown solution.
Potassium Iodide is oral antithyroid agent used in the prevention of radioactive iodine uptake into the thyroid gland during a nuclear radiation emergency. Potassium Iodide may be used as an adjunct to other antithyroid agents in the treatment of hyperthyroidism and thyrotoxicosis and preoperatively to induce thyroid involution.
Potassium iodide is a colourless to white salt with a bitter taste. It is used as a nutritional supplement, a thyroid medication, and a radiation shield. Learn more about its chemical and physical properties, structure, and preparation.
When potassium iodide is dissolved in water, it forms an aqueous solution. The colour of the solution depends on the concentration of potassium iodide. - At low concentrations, the solution is colourless. - As the concentration increases, the solution turns pale yellow. - At higher concentrations, the solution turns dark yellow or brown.
The compound potassium iodide is a white crystalline salt having the chemical formula ${\text{KI}}$ . It is an oral antithyroid agent used in the prevention of radioactive iodine uptake. This compound absorbs water less readily than sodium iodide.
Potassium iodide solution is typically colorless. However, in certain concentrations or conditions, it can appear slightly yellow or pale yellow due to the presence of impurities.
