Potassium Iodate (CAS 7758-05-6) is an inorganic iodine salt supplied as white crystals or powder with a high iodine content of about 59%, used to iodize table salt, as an oxidizing agent in analytical chemistry, and for controlled iodine supplementation in pharmaceuticals. It dissolves in water to yield mildly acidic solutions.
