Description Sodium sulfite is a white crystalline powder with a
sulfurous odor. It is soluble in water and slightly soluble in
alcohol. Its chemical formula is Na2SO3, and its molecular weight
is 126.04 g/mol. Sodium sulfite is a reducing agent and can easily
lose sulfur dioxide gas when exposed to air. Sodium sulfite is
commonly used as a reducing agent and antioxidant in various
industries, including food and beverage, water treatment, and
photography. It is also used in the production of paper and pulp,
as well as in the textile industry for dyeing and bleaching
processes. Sodium sulfite is known to be a skin and eye irritant
and can be harmful if ingested or inhaled in large quantities.
