Sodium hydrosulfite (Sodium dithionite, Sodium hypodisulfite, Na2S2O4) is a white crystalline sodium salt. It decomposes in the presence of atmospheric oxygen to afford sodium hydrogen sulfate. It has been prepared by reducing sodium hydrogen sulfite in sulfurous ACID solution with zinc.It is widely used for the decolorization prior to dyeing of cloths in the textile industry.
Molecular formula: Na2S2O4
Appearance: Sodium hydrosulfite is also known as sodium dithionite, and is white crystalline powder or yellowish. It is soluble in sodium hydroxide solution and slightly soluble in ethanol.Powdered anhydrous sodium hydrosulfite with a small amount of water may ignite in air by the heat of decomposition.
