Colorless or white cubic crystals. Odorless, with a strong, salty taste. Soluble in water, soluble in ethanol, methanol, acetone, glycerin and liquid ammonia, slightly soluble in ether. Its aqueous solution is neutral or slightly alkaline.


(1.) Commonly used as analytical reagents, and also used in the preparation of photographic photosensitive emulsifiers and in the pharmaceutical industry
(2.) Used in photosensitive emulsion, soap, lithography, organic synthesis, medicine, food additives, etc.
(3.) Potassium iodide is a permitted food iodine fortifier. It can be used for table salt, the dosage is 30-70mg/kg; the dosage in infant food is 0.3-0.6mg/kg.
(4.)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. As a component of thyroxine, iodine participates in the metabolism of all substances in livestock and poultry and maintains heat balance in the body. Chemicalbook is an essential hormone for the growth and reproduction of livestock and poultry. It can improve the growth performance of livestock and poultry and promote body health. If the animal body lacks iodine, it will lead to metabolic disorders, body disorders, goiter enlargement, affecting nerve function, coat color quality, and digestion and absorption of feed, eventually leading to slow growth and development.
