About Sodium arsenate, GR 98%+

Vaqora Chemicals supplies Sodium arsenate in AR grade, an alkali metal compound registered under CAS number 10048-95-0, specified at ≥98% purity. With the molecular formula AsH15Na2O11, it has a molar mass of 312.01 g/mol. Systematically, it is named disodium. Hydrogen arsorate. Heptahydrate. Common synonyms include Disodium hydrogen arsenate heptahydrate and di-Sodium hydrogen arsenate heptahydrate.

In its supplied form it is powder to crystals. Literature values give a melting point of 180 °C and a density of 1.88 g/cm3. Its solubility is described as soluble in water and glycerol. Store sealed in a dry, well-ventilated location away from incompatible materials. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Typical applications include dyes and pigments manufacture and materials research. Buyers come mainly from academic and industrial research.

Standard pack sizes are 25 g, 100 g, 250 g and 500 g, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
