SODIUM METATUNGSTATE CAS#12141-67-2
Sodium metatungstate is a stable and valuable tungstate salt. In aqueous solution, its metatungstate anions can react with a range of metal ions to generate precipitates of diverse tungsten compounds. It is also capable of participating in redox reactions, where the valence state of tungsten may shift under given conditions.
