Potassium iodate (KIO3) is an inorganic ionic compound consisting of potassium cations and iodate anions. It appears as a white crystalline solid and serves as a stable source of iodine. Primary applications include fortification of table salt to prevent iodine deficiency disorders such as goiter and cretinism. It functions as a strong oxidizing agent in analytical chemistry for standardization of thiosulfate solutions in iodometry. The compound decomposes at high temperatures releasing oxygen and iodine vapors. It exhibits moderate solubility in water (approximately 9.2 g/100 mL at 25 °C) but remains largely insoluble in alcohols and nonpolar solvents including fats. Regulatory bodies approve its use in food-grade salt at controlled concentrations.
