Product Details

Products Description of Sodium tungstate dihydrate CAS#10213-10-2

White crystalline powder or colorless to white rhombic crystals, with the attribute of being distinctly soluble in water. At 25℃, its solubility in water is about 74.2g/100mL, and its aqueous answer is weakly alkaline. Insoluble in ethanol, barely soluble in ammonia. It is steady at ordinary temperature and pressure, however beneath heating conditions, it will step by step lose its crystalline water. It can react with robust acids to structure tungstic acid precipitate.
