POTASSIUM IODATE
Potassium Iodate tablets are used at the time of a nuclear emergency; the tablets stop the thyroid gland (situated in your neck) taking up radioactive iodine, which may be released into the environment following a nuclear accident. Radioactive Iodine is harmful and especially dangerous to babies and children.
Potassium iodate is sometimes used for iodination of table salt to prevent iodine deficiency. Because iodide can be oxidized to iodine by molecular oxygen under wet conditions, US companies add thiosulfates or other antioxidants to the potassium iodide
Potassium iodate is often used as a reference material to standardize a sodium thiosulfate solution which is a familiar titrant for redox titrations.
