Product Description

Sodium Sulfite 97%
Molecular formula: Na2SO3
Molecular weight:126.04
Description:

Sodium sulfite 97% is a white powder or hexagonal prismatic crystal. Density 2.633g/cm3. When heated to red heat, it decomposes. Very stable and not easily oxidized. Easy to dissolve in water, slightly soluble in alcohol, insoluble in liquid chlorine and ammonia. Strong reducing agent. It is easy to oxidize into sodium sulfate under humid air and sunlight. React with sulfur dioxide to produce sodium bisulfite. The sulfur dioxide or sulfur combustion in sulfuric acid tail gas produced by the absorption contact method of soda ash solution generates sulfur dioxide gas, obtaining a concentrated solution of sodium sulfite, which is crystallized from the concentrated solution at 95-100 ºC.
