Sodium dithionite is an inorganic sodium salt that is the disodium salt of dithionous acid. It has a role as a bleaching agent and a reducing agent. It contains a dithionite(2-).
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.
