About Sodium Metabisulphite

Accessible in white powder form, Sodium Metabisulphite has maximum 10 ppm ferrous content. This chemical easily dilutes in water and glycerol and its storage life is 2 years. This substance is slightly soluble in C2H5OH and readily dilutes in eethanol. It also dilutes in sodium bisulfite. It is accessible in 98% pure form and its molar mass is 190.095g/mol. When exposed to water, Sodium Metabisulphite smells like sulphur dioxide. Density of this chemical is 1.4 g/cm3. It tends to decompose when heat is applied.
