Sodium sulfite with CAS 7757-83-7 is an inorganic compound. It is a white granular powder at room temperature with a sulfur dioxide odor. It is stable when dry and sensitive to moisture. It is soluble in water and glycerin, insoluble in ethanol, and its aqueous solution is alkaline to litmus paper and phenolphthalein. It reacts with acid to produce toxic sulfur dioxide gas. The pH of a 1% aqueous solution is 8.3~9.4, and it has strong reducing properties. It decomposes into sodium sulfide and sodium sulfate when heated, and gradually oxidizes to sodium sulfate when placed in the air. In nature, it exists in three forms: anhydrous sodium sulfite, heptahydrate sodium sulfite, and decahydrate sodium sulfite. Among them, anhydrous sodium sulfite is the least susceptible to oxidation.
