Product Description

Sodium Tungstate Dihydrate with CAS 10213-10-2

Sodium tungstate is a kind of chemicals, colorless crystal or white crystalline powder, weathering in dry air, 100 ℃ when losing crystal water, soluble in water, insoluble in ethanol, relative density 3.23 ~ 3.25, melting point 698 ℃ (no water).
Sodium tungstate is a colorless crystal or white rhombic crystal with shiny flake crystal or crystalline powder. Sodium tungstate is soluble in water, slightly alkaline in water, insoluble in ethanol and slightly soluble in ammonia. Weathering in the air. Heated to 100 ℃ water of crystallization and become lost without water. React with acid (except hydrofluoric acid) to generate insoluble in water of the yellow tungsten acid, and phosphoric acid or phosphate reaction generated phosphor tungsten heteropoly acid complex, and tartaric acid, citric acid, oxalic acid and organic acid reaction to generate organic acid complex.
