Hydrosulfite De Sodium

Sodium Dithionite (also known as Sodium Hydrosulfite) is a white crystalline powder with a sulfurous odor as Inorganic Product. Although it is stable in dry air, it decomposes in hot water and in acid solutions. Being water-soluble, Hydrosulfite De Sodium is used as a reducing agent in some industrial dyeing processes. In the case of sulfur dyes and vat dyes, an otherwise water-insoluble dye can be reduced into a water-soluble alkali metal salt (e.g. indigo dye). Sodium Hydrosulfite 90% can also be used for water treatment, gas purification, cleaning, and stripping. Sodium Hydrosulphite 88% Hydrosulfite has also been applied as a sulfonating agent. In addition to the textile industry, this compound is used in industries concerned with leather, foods, polymers, photography, and many others
