Sodium Hydrosulfite is a white crystalline powder with a weak sulfurous odor. It is a sodium salt of dithionous acid. Although it is stable under most conditions, it will decompose in hot water and in acid solutions.  

Sodium Hydrosulfite is used as a reducing agent in aqueous solutions, industrial dyeing processes, water treatment, gas purification, cleaning, and stripping. In addition to the textile industry, this compound is used in industries concerned with leather, foods, polymers, photography, and many others.
