Product Description

The chemical formula NaI. Molecular weight 149.89. Colorless cubic crystal or white granular matter. It tastes salty and slightly bitter. The melting point is 651ºC, the boiling point is 1304ºC, the relative density is 3.665(4ºC), 3.607(25ºC), and the refractive index is 1.7745. It has strong hygroscopicity. In the air gradually hygroscopic to the water content of 5%, can be released by air oxidation of iodine and brown, the aqueous solution is slightly alkaline, also has the same change, can be slightly added alkali to maintain stability. The pH of aqueous solution is 8 ~ 9.5. Should be kept away from light.
