Sodium metavanadate is the

inorganic compound In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemi ...

with the formula NaVO₃. It is a yellow, water-soluble salt. Sodium metavanadate is a common precursor to other vanadates. At low pH it converts to sodium decavanadate. It is also precursor to exotic metalates such as �-PV₂W₁₀O₄₀sup>5-, �-PVW₁₁O₄₀sup>4-, and �-PV₂W₁₀O₄₀sup>5-.

Minerals

Sodium metavanadate occurs as two minor minerals, metamunirite (

anhydrous A substance is anhydrous if it contains no water. Many processes in chemistry can be impeded by the presence of water; therefore, it is important that water-free reagents and techniques are used. In practice, however, it is very difficult to achi ...
