Usage:  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.
