Opis
Ammonium Iodate
Other Names: Ammonium salt of iodic acid
CAS Number: 16919-19-0
Chemical Formula: NH₄IO₃
Molar Mass: 176.95 g/mol
Appearance: White to pale yellow crystalline solid
Description:
Ammonium iodate is an inorganic salt composed of ammonium (NH₄⁺) and iodate (IO₃⁻) ions. It is known for being a strong oxidizer and is sensitive to heat, friction, and reducing agents. Due to its reactive nature, it is primarily used in laboratory-scale reactions and research involving oxidation chemistry.
