Sodium Metabisulite / SMBS as Bleaching Agent in Making Cotton and
It is white or tiny yellow crystal powder. Its relative density is
1.4. The solubility is 54g/100mlwater at 20°C or 81.7g/100mlwater
at 100°C , and the solution show acidity. It can solute in
glycerine and little in alcohol. When exposed in air , it will
oxidized into sodium sulfate , and can react with strong acid into
sulfur dioxide gas and the salts. It is deliquescent , and will
decompose when heated to 150°C.
