Sodium hydrosulfite, also known as sodium dithionite, is a powerful reducing agent widely used in industrial applications. Its primary function is as a bleaching agent in the textile and paper industries, where it effectively removes color from fabrics and paper pulp, making it crucial for achieving white and colorfast textiles and paper products. Additionally, sodium hydrosulfite is employed in various chemical processes, such as in the production of certain polymers and in water treatment to remove excess chlorine. Its remarkable reducing properties, which allow it to decolorize and dechlorinate, make sodium hydrosulfite a valuable chemical compound in multiple industrial sectors.
