sodium iodide

[′sōd·ē·əm ′ī·ə‚dīd]
(inorganic chemistry)
NaI A white, air-sensitive powder, deliquescent, with bitter taste; soluble in water, alcohol, and glycerin; melts at 653°C; used in photography and in medicine and as an analytical reagent.

Sodium Iodide


Nal, a salt; colorless crystals. Density, 3.665 g/cm3; melting point, 662°C. Upon prolonged exposure to light, it turns yellow because of oxidation by atmospheric oxygen and liberation of free iodine. Sodium iodide is hygroscopic. Solubility in water, 64.1 percent at 20°C and 75.1 percent at 100°C. At ordinary temperature, NaI · 2H2O crystallizes from aqueous solutions. Sodium iodide is obtained by means of an exchange reaction between Fe3 I8 and Na2CO3 and is used for medicinal purposes as an iodine preparation.
