Chemical & Physical Properties

Sodium sulfite is a white crystalline inorganic salt with stable physical properties at room temperature. It dissolves quickly in water to form a clear solution with weak alkalinity. The product has mild and controllable reducibility, capable of removing residual chlorine and dissolved oxygen in water. It is non toxic and low corrosive, with stable reaction performance during industrial use. It will be gradually oxidized to sodium sulfate when exposed to air, and reacts with acid to release sulfur dioxide gas.

Main Applications

In water treatment, it serves as oxygen scavenger and dechlorinating agent to purify industrial circulating water and boiler water. In textile and paper industry, it acts as gentle bleaching agent to protect fiber and paper texture. It also works as antioxidant and preservative in chemical synthesis, food processing and pharmaceutical production, effectively preventing raw material oxidation and deterioration.

Product Features

Continuous and stable reduction effect avoids excessive reaction damage. Fast water dissolution improves industrial operating efficiency. Low impurity content ensures clean reaction results. Mild property reduces equipment corrosion and application risks, meeting standard industrial production requirements.
