>> Properties and uses

Properties:

Potassium iodide is colorless or white crystal, easily soluble in water, soluble in ethanol, methanol, acetone, glycerin and liquid ammonia, and slightly soluble in ether. There is slight deliquescence in wet air, and it is easy to be oxidized when exposed to the air. It gradually turns yellow due to iodine release. Light and moisture can accelerate its decomposition.


Uses:

1. Potassium iodide can be used as analytical reagent, chromatography and drop analysis.

2. Potassium iodide is the raw material for making iodide and dye.

3. Potassium iodide can be used as photographic emulsion

4. Potassium iodide is a food iodine fortifier allowed to be used as a nutritional supplement (iodine fortifier) in the food industry.

5. Potassium iodide is also used in pharmaceutical industry, soap, lithography, organic synthesis, medicine, food additives, etc.
