CAS NO : 7757-83-7
EC NO : 231-821-4
Molecular Formula : Na2SO3
Main Specifications :
Synonyms : Sodium sulfite anhydrous;Sodium sulphite;anhydrous sodium sulfite;Sodium sulfite ,anhydrous;
It's white crystal or powder, no foul. Soluble in water (When 0 degree, 12.55g/100ml water; When 80 degree,283g/100ml water), at 33.4 degree the maximum solubility of about 28%, the aqueous solution is alkaline. Slightly soluble in alcohol, insoluble in liquid chlorine, ammonia. Easily oxidized in air into sodium, when the temperature is decomposed into sodium sulfide. As a strong reducing agent, it reacts with sulfur dioxide into sodium bisulfate, and with strong acid into corresponding salts.
anhydrous sodium sulfite granular
White monoclinic system crystalline powder. Soluble in water, alkaline aqueous solution. Soluble in glycerin, insoluble in ethanol.
