Potassium iodide is used to make organic compounds, chemical reagents, etc. The so-called iodized table salt that we often eat is the addition of potassium iodide or potassium iodate (in the ratio of one part in 20,000) to common salt (pure sodium chloride). Potassium iodide has antifungal activity. It is clinically used to treat sporotrichosis, dysentery, persistent erythema nodules and vasculitis. Potassium iodide is the raw material for the preparation of iodide and dye.
