Sodium Hydrosulphite (also called sodium dithionite) is a water-soluble salt, and can be used as a reducing agent in aqueous solutions. It is used as such in some industrial dyeing processes, primarily those involving sulphur dyes and vat dyes, where an otherwise water-insoluble dye can be reduced into a water-soluble alkali metal salt (e.g. indigo dye). The reduction properties of Sodium Hydrosulphite also eliminate excess dye, residual oxide, and unintended pigments, thereby improving overall colour quality.
Sodium Hydrosulphite can also be used for water treatment, gas purification, cleaning, and stripping. It can also be used in industrial processes as a sulfonating agent or a sodium ion source. In addition to the textile industry, this compound is used in industries concerned with leather, foods, polymers, photography, and many others. It is also used as decolourising agent in organic reactions.
