What Is Sodium Sulfite Anhydrous and How to Buy Sodium Sulfite Anhydrous?
What Is Sodium Sulfite Anhydrous?
The inorganic compound sodium sulfite anhydrous (sodium sulfite) has the chemical formula Na2SO4. It's a white, water-soluble substance employed as an antioxidant and preservative in the food industry. Although a heptahydrate exists, it is less practical due to its increased sensitivity to oxidation by air.

Sodium Sulfite Anhydrous Uses
To keep dried fruit from discoloring, sodium sulfite is used as a preservative. In the chemical industry, it is used as a sulfonation and sulfomethylation agent. Its other uses are:
- The pulp and paper sector is the primary user of sodium sulfite.
- It is employed as a bleaching, desulfurizing, and dechlorinating agent in the textile sector as a reducing agent (e.g., in swimming pools).
- Its reducing qualities are used as a preservative to avoid the discoloration of dried fruit and preserve meats.
- Sulfonation and sulfomethylation agents employ it as a reagent.
- It is what's utilized to make sodium thiosulfate.
Is Sodium Sulfite Anhydrous Safe?
Acute and prolonged exposure to the acidic breakdown of sodium sulfite anhydrous may generate poisonous and dangerous sulfur oxide gases, including sulfur dioxide, which may cause lasting respiratory problems. Industrially, sodium sulfite is created by reacting sulfur dioxide with a sodium carbonate solution.
How Is Sodium Sulfite Anhydrous Made?
Sulfite is made by treating a sodium hydroxide solution with sulfur dioxide. In warm water, Na2SO3 precipitates as a white solid. More SO2 dissolves the solid to form disulfite, which crystallizes on cooling.
