Chemical stability of ammonium metatungstate
Ammonium metatungstate is stable at room temperature and pressure, but it will decompose at high temperature. The decomposition temperature varies depending on the degree of completion of the decomposition reaction. Generally, dehydration and deammoniation begin at 200-300℃, and finally completely decompose into tungsten trioxide (WO₃) at above 600℃.
Oxidizing and reducing properties of ammonium metatungstate
Ammonium metatungstate has oxidizing and reducing properties, but is stable under general conditions. Under specific conditions, such as when reacting with other reducing agents or oxidizing agents, it can show its oxidizing or reducing properties.
Acidity and alkalinity of ammonium metatungstate
The aqueous solution of ammonium metatungstate is weakly acidic.
Chemical reaction of ammonium metatungstate
Ammonium metatungstate can react chemically with a variety of substances, such as forming precipitation with metal ions, reacting with reducing agents to generate metallic tungsten, etc.
Chemical safety of ammonium metatungstate
Ammonium metatungstate should be stored and used with care because it is a dangerous substance and is irritating. Avoid direct contact with skin and eyes, and prevent inhalation of dust.
Ammonium metatungstate may cause combustion or explosion when encountering organic matter, reducing agents and combustible substances, so it should be kept away from fire and heat sources.
