Potassium iodide is white cubic crystal or powder. It is slightly hygroscopic in moist air, 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 was 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 glycerol, 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. The relative density is 3.12. The temperature of 680 ° C. The boiling point of 1330 ° C. The approximate lethal dose (rat, vein) was 285 mg/kg. It is widely used in the volumetric analysis of iodometric methods to prepare titration solutions. Mediums such as Beredes, Modified White, MS, and RM are prepared in haplotypes. Fecal examination, etc. Photo. Pharmaceutical.

Potassium Iodide is a source of iodine and a nutrient and dietary supplement. it exists as crystals or powder and has a solubility of 1 g in 0.7 ml of water at 25°c. it is included in table salt for the preven- tion of goiter. Potassium Iodide is used primarily used in the treatment of radiation poisoning due to environmental contamination by iodine-131. It is also manufacture of photographic emulsions; in animal and poultry feeds to the extent of 10-30 parts per million; in table salt as a source of iodine and in some drinking water; also In animal chemistry. In medicine,potassium iodide is used to regulate the thyroid gland.
Potassium iodide was first used as the primary halide in Talbot’s calotype process, then in the albumen on glass process followed by the wet collodion process. It was also used as a secondary halide in silver bromide gelatin emulsions, animal feeds, catalysts, photographic chemicals, and for sanitation. Potassium iodide is produced by reaction of potassium hydroxide with iodine. The product is purified by crystallization from water. Potassium iodide is ionic compound which iodine ions and silver ions can form yellow precipitate silver iodide (when exposes to light, it can decompose, it can be used to make high-speed photographic film), silver nitrate can be used to verify the presence of iodine ions.
