H.S Code:.
White or light yellow crystal powder a strong smell of sulfur dioxide relative density is 1.4 easy to dissolve in water(20A C54g/100ml water 100A C81.7g/100ml water) and glycerin water solution. It has acidity and its solubility will become large while raising the temperature and is less to dissolve in ethanolDamp easily decomposed when exposed in air easily oxidized into sodium sulfate. And acid contact and the generated sulfur dioxide released corresponding salts. Heated to 150 A C decomposition.
