Sodium Metabisulfite Food Grade

Name:Sodium Metabisulfite Food Grade
Alias:Sodium pyrosulfite food grade
Molecular formula:Na2S2O5
Molecular weight: 190.10
Sodium Mrtabisulfite  is white or yellowish crystalline powder, relative density: 1.4; soluble in water(20°C 54g/100ml of water; 100°C 81.7g/100ml of water). Aqueous solution is acid; soluble in glycerin, slightly soluble in ethanol. Will be decomposed in humid conditions, and oxidized into sodium sulfate in open air; will release sulfur dioxide when contacting strong acids; will be decomposed at 150°C.
