Sodium Iodide 7681-82-5

Sodium iodide is an inorganic compound with the chemical formula NaI and a molecular weight of 149.89. It is a colorless cubic crystal or white granular substance, formed by the reaction of sodium carbonate or sodium hydroxide with hydroiodic acid, followed by evaporation of the solution. It exists in anhydrous, dihydrate, and pentahydrate forms. It is used as a raw material for iodine production and has applications in medicine and photography. Acidic solutions of sodium iodide exhibit reducing properties due to the formation of hydroiodic acid. It has a salty and slightly bitter taste, is soluble in glycerol, and is highly hygroscopic. It gradually absorbs moisture from the air until its water content reaches 5%. It can be oxidized by air to release iodine and turn brown. Aqueous solutions are slightly alkaline and exhibit the same change; a slight addition of alkali can stabilize it. The pH of the aqueous solution is 8–9.5. It should be stored in a light-proof, airtight container.
