What is Sodium iodate?

Chemical properties

white crystalline powder

The Uses of Sodium iodate

Sodium iodate is used in animal feed, food industry. It is utilized in the manufacture of disinfectants, antiseptics and deodorants. It acts as a significant part in the oxidation of aromatic, aliphatic, and alicyclic thiols. Potassium tetrahydroborate and sodium iodate in acidic aqueous solution react with cadmium to generate chemical vapor, which is useful for atomic fluorescence spectrometry application.

The Uses of Sodium iodate

Antiseptic, disinfectant, feed additive reagent.
