Sodium Metabisulfite is also named Sodium Pyrosulfite, Sodium
Metabisulfite is white or slight yellow crystalline powder, with
strong smell of SO2, the proportion of 1.4, soluble in water,
aqueous solution of Sodium Metabisulfite is acidic, Sodium
Metabisulfite contacts with strong acids, released SO2 and
generates sodium sulfate, commonly known as Glauber's salt. For a
long time in the air, Sodium Metabisulfite can be oxidized into
Na2S2O6, so Sodium Metabisulfite can not be stored for a long time.
Above 150 degrees Celsius, Sodium Metabisulfite can decompose of
SO2. Soluble in water and glycerin, slightly soluble in ethanol.
Soluble in water, Sodium Metabisulfite generates into stable sodium
bisulfite, pH under 1% aqueous solution ranged from 4.0 to 5.5.
