Description and Uses

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.
