The Introductction of Potassium Iodide :
Potassium iodide is colorless or white cubic crystals. Odorless, with a strong bitter and salty taste. It is easily soluble in water, soluble in ethanol, glycerin. Its aqueous solution is neutral or slightly alkaline.
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.
The Application & Function of Potassium Iodide :
Potassium iodide is often used as an analytical reagent, and also used in the preparation of photographic emulsifiers and in the pharmaceutical industry.
Potassium iodide is used in photosensitive emulsion, soap, lithography, organic synthesis, medicine, food additives, etc.
Potassium iodide is an allowable food iodine fortifier. my country stipulates that it can be used in foods for infants and young children, and the dosage is 0.3-0.6mg/kg. It can also be used for table salt with a dosage of 30-70mL/kg.
