I s potassium iodide soluble Potassium iodide is a white cubic crystal or powder. Potassium iodide is slightly hygroscopic in moist air. Potassium iodide precipitates free iodine for a long time and turns yellow, and can form a trace amount of iodate. Light and moisture can accelerate decomposition. 1 g of potassium iodide can be dissolved in 0.7 ml of water, 0.5 ml of boiling water, 22 ml of ethanol, 8 ml of boiling ethanol, 51 ml of absolute ethanol, 8 ml of methanol, 7.5 ml of acetone, 2 ml of glycerin, and about 2.5 ml of ethylene glycol. Its aqueous solution is neutral or slightly alkaline and can dissolve iodine. The aqueous solution will also oxidize and change to a yellow color, which can be prevented by adding a small amount of alkali. Its relative density is 3.12, the melting point is 680 ℃, and the boiling point is 1330 ℃. Its approximate lethal dose (rat, vein) is 285 mg/kg. It is widely used in the volumetric analysis of iodometric methods to prepare titrants. Mediums such
