stability
It will not decompose if used and stored according to specifications. Slightly soluble in hot water, soluble in alkali, hydrofluoric acid and ammonia, almost insoluble in acid.

Dehydration begins at 100℃, boiling point 1473℃. It is burned at high temperature and converted to tungsten trioxide. Insoluble in cold water and most acids, slightly soluble in hot water, soluble in alkali, hydrofluoric acid and ammonia. Solution of n-tungstate or paratungstate is treated with dilute acid to obtain colloidal tungstate, which contains different amounts of water and has greater solubility and activity in water than yellow tungstate. Powdery white tungstic acid has higher activity than yellow tungstic acid. It can be prepared by adding tungstate solution to dilute nitric acid solution.

Yellow tungstic acid is used to make metallic tungsten powder, and white tungstic acid in powder form can be used to prepare metatungstate and tungsten-containing heteropoly salts.

Water is insoluble
