Description and Uses

Potassium iodate is an iodine-rich salt with the formula KIO3. In hot and humid climates, iodine vapor is hydrolyzed due to the hygroscopicity of potassium iodide. Compared to potassium iodide, potassium iodate is more stable and has a longer shelf life. It is a potent blocker of radioactive iodine uptake by the thyroid gland.

Oxidizing agent in volumetric chemical analysis; as maturing agent and dough conditioner.
