The chemical properties of ammonium metatungstate (AMT) are as follows:
Acidity: Ammonium metatungstate is an acidic compound that can dissolve in water and release acidic hydrogen ions.
Oxidation: Ammonium metatungstate exhibits certain oxidation properties under some conditions, and can undergo oxidation reactions with other substances.
Thermal decomposition: Under high temperature conditions, ammonium metatungstate can undergo a thermal decomposition reaction, decomposing to generate tungsten oxide (tungsten oxide) and ammonia gas.
Solubility: Ammonium metatungstate has good solubility and can be dissolved in water to form a solution. It can also be dissolved in some organic solvents, such as alcohols, ketones, etc.
Reducibility: Under proper conditions, ammonium metatungstate can be reduced to low-valence compounds of tungsten, such as tungsten oxide (W2O3) or tungsten powder.
Acid hydrolysis reaction: Ammonium metatungstate can react with acid to form tungstate. Commonly used acidolysis agents include sulfuric acid, nitric acid, etc.
The chemical properties of ammonium metatungstate are affected by environmental conditions and other reactants. Specific chemical properties can be measured and determined depending on experimental conditions and specific reactions.
