Sodium Hydrosulphite
Sodium dithionite (also known as sodium hydrosulfite) is a white crystalline powder with a sulfurous odor. Although it is stable in dry air, it decomposes in hot water and in acid solutions. Except where otherwise noted, data are given for materials in their standard state (at 25 degree C, 100 kPa).

Strong Reducing Agent
Remarks
Sodium hydrosulfite is a versatile chemical and is used mainly in textile dyeing, manufacturing of pulp and paper, commercial bleaching agent, bleaching of foodstuffs and as a reducing agent in hair treatment. Sodium hydrosulfite is used as a reducing agent in aqueous solutions, sulfonating agent, chelating agent and decolorizing agent in organic reactions.
Sodium Hydrosulfite finds application in water treatment, gas purification, cleaning, leather, polymers, photography, and many others. It is involved in chemical enhanced oil recovery to stabilize polyacrylamide polymers against radical degradation in the presence of iron.
Sodium Hydrosulfite plays an important role to determine the iron content in soil chemistry.
