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. Thus solutions of sodium dithionite cannot be stored for a long period of time.


While the applications for this chemical workhorse are as vast and as varied as the industries that use it, in most cases, sodium hydrosulfite performs one of the following three roles:
As a reducing agent, hydrosulfite chemically reduces other components by donating an electron or electrons
As a sulfonating agent, hydrosulfite adds sulfur to another chemical compound
As a cation source, hydrosulfite adds a cation, or sodium, to a product system
