Sodium metatungstate is a stable and important tungstate salt. In aqueous solutions, its metatungstate ions can interact with various metal ions to form different tungsten compound precipitates. Additionally, it can undergo certain redox reactions, allowing the tungsten valence to change under specific conditions.
