It is soluble in water and also glycerol, insoluble in ethanol, as well as the liquid remedy is alkaline. Its liquid option is alkaline to base test paper as well as phenolphthalein. It reacts with acid to create poisonous sulfur dioxide gas. The pH of 1% aqueous service is 8.3 ~ 9.4, as well as it has solid reducibility. It is disintegrated right into sodium sulfide as well as sodium sulfate when heated, and gradually oxidized right into sodium sulfate when put airborne. In nature, there are 3 forms of anhydrous sodium sulfite, salt sulfite heptahydrate as well as sodium sulfite decahydrate, of which anhydrous sodium sulfite is the most difficult to be oxidized.

Sodium sulfite anhydrous(Na2SO3), as a soluble sodium salt of sulfite, has the homes of bleaching, desulfurization and dechlorination, and is commonly used in numerous areas. Because of its bleaching activity, it is primarily utilized in the pulp as well as paper sector. It can be used as a great additive to help keep the fresh look of top quality items. Furthermore, salt sulfite is a component of lots of medications, which can properly preserve the efficiency as well as security of medications. It can also be made use of as a deoxidizer for water therapy, flue gas desulfurization, designer preservation, and so on.
