Is Potassium Iodide Soluble? Is 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 ° C, and the boiling point is 1330 ° C. 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 as Beredes, Modified White, MS and RM are formulated in haplotypes. It can be used for stool inspection, photography, and pharmaceuticals. If there is insolubilization or temperature in the experiment, please adjust it properly.

Potassium iodide is often used as a synergist for steel pickling inhibitors or other corrosion inhibitors, and as an analytical reagent, such as an iodine standard solution as an auxiliary reagent. It is also used as a photo emulsifier and feed additive. It can be used in the pharmaceutical industry. The so-called iodized edible salt that we often eat is to add potassium iodide or potassium iodate (in proportion to 20,000) to ordinary salt (pure sodium chloride).
