Introduction to the solubility and use of sodium metabisulfite

Solubility of sodium metabisulfite: soluble in water, the aqueous solution is acidic (54g/100ml water at 20℃; 81.7g/100ml water at 100℃). Soluble in glycerin, slightly soluble in ethanol. The relative density is 1.4. It is soluble in water, soluble in glycerin, and slightly soluble in ethanol. It is easily decomposed by moisture and easily oxidized to sodium sulfate in exposed air. Contact with strong acids releases sulfur dioxide and generates corresponding salts. Heated to 150 ℃ decomposition.

Sodium metabisulfite is mainly used for the production of insurance powder, sulfamethazine, analgin, caprolactam, etc., as well as the purification of chloroform, phenylpropyl sulfone and benzaldehyde. It is used as a fixer ingredient in the photographic industry. The perfume industry is used to produce vanillin. Used as preservative in brewing industry, rubber coagulant and dechlorinating agent after cotton bleaching. Organic intermediates, dyes, and leather are used as reducing agents. Used as electroplating industry, oil field wastewater treatment, and as a mineral processing agent in mines.
