Usage:

The role of anhydrous sodium sulfite is extensive, it is in the pharmaceutical industry, paper making, leather tanning and dyeing industries and plant fiber bleaching, food, etc have a very important role. Addition of anhydrous sodium sulfite is also used to film developing, bleaching agents, printing and dyeing industry as a deoxygenation agent.

Nature:

White crystal or powder; no foul. Soluble in water, very slightly soluble in ethanol, almost insoluble in ether. White hexagonal prismatic crystals, soluble in water (0 ℃ 12.54g/100ml water; 80 ℃ when the 283g/100ml water), in 33.4 ℃ The maximum solubility of about 28% when the aqueous solution is alkaline, PH value is about 9 ~ 9.5 . Slightly soluble in alcohol, insoluble in liquid chlorine, ammonia. Easily oxidized in air sodium, when the temperature is decomposed into sodium sulfide. To strengthen the reducing agent, reacts with sulfur dioxide, sodium bisulfite, reacted with the acid salt.
