Molecular Structure:

Product description: CAS No.: 7757-83-7 Molecular Formula: Na2SO3 Molecular Weight: 126.04 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 (when 0°C 12.54g/100ml water; When 80°C 283g/100ml water), in 33.4°C The maximum solubility of about 28% when the aqueous solution is alkaline. 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.
