Sodium sulfite anhydrous, with the chemical formula Na2SO3, appears as white powder or crystals. It is highly soluble in water, and its aqueous solution is alkaline. It will gradually oxidize to sodium sulfate in the air. It has strong reducing properties and is widely used as a reducing agent, deoxidizer and bleaching agent in industries such as papermaking, dyeing and printing, food, medicine and water treatment. For instance, it helps remove lignin in papermaking, protects fibers and whiten them during dyeing and printing, and serves as a preservative and antioxidant in food. Its applications are diverse and significant.
