Tungstic acid

Tungstic acid refers to hydrated forms of tungsten trioxide, WO3.

Molecular species akin to sulfuric acid, i.e. (HO)2WO2 are not observed.

The solid-state structure of WO3·H2O consists of layers of octahedrally coordinated WO5(H2O) units where 4 vertices are shared.

It may also be prepared from the reaction between hydrogen carbonate and sodium tungstate.

It can also be obtained from pure tungsten by reaction with hydrogen peroxide.

E.g. water Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
