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).
APPLICATION
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, Technical Grade, 70% Active Matter suitable for RO Plant. Sodium hydrosulfite, technical grade, 85%
Sodium Hydrosulfite, also known as sodium dithionite or hydros, has a formula of Na2S2O4. It is a white crystalline powder and exists in both the anhydrous and dehydrated forms. Sodium hydrosulfite has a Powerful Reducing capacity and allows vat dyes to be reduced readily at room temperatures. It can also be used as antioxidants in hair treatment processes.
Sodium hydrosulfite is stable when dry, but will slowly be oxidized by air. Even with the absence of air, it will be deteriorated and hence it cannot be kept for long and has a comparatively shorter shelf life. When sodium hydrosulfite is wet and in the absence of oxygen, it is unstable and will be decomposed to sodium thiosulfate and sodium bisulfite.
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.
