naatriumjodiid

Naatriumjodiid, also known as sodium iodide, is an inorganic compound with the chemical formula NaI. It is a white crystalline solid that is highly soluble in water and alcohol. In its pure form, it is odorless, but impure samples can sometimes have a faint odor due to the presence of free iodine.

Naatriumjodiid is a salt formed from the reaction of sodium hydroxide with hydroiodic acid. It is a key source of iodide ions and is used in various applications. One of its most significant uses is in medicine, where it is employed as a source of iodine for treating iodine deficiency disorders and as a radiocontrast agent in medical imaging. It can also be used in the treatment of certain thyroid conditions.

Industrially, naatriumjodiid finds application in photography, where it is used in the preparation of light-sensitive silver iodide. It also serves as a catalyst in organic synthesis and as a stabilizer in some chemical processes. In animal feed, it is added as a nutritional supplement to prevent iodine deficiency. The compound is hygroscopic, meaning it readily absorbs moisture from the air, and should be stored in airtight containers.
