        Basic Information

        Anhydrous sodium sulfite, white crystal or powder; odorless. This product is soluble in water, slightly soluble in ethanol, and almost insoluble in ether. Dissolved in water (12.54g / 100ml water at 0 ° C; 28.3g / 100ml water at 80 ° C), solubility at 33.4 ° C is about 28%, aqueous solution is alkaline, PH value is about 9 ~ 9.5. Slightly soluble in alcohol, insoluble in liquid chlorine, ammonia. It is easily oxidized to sodium sulfate in the air and decomposed into sodium sulfide in case of high temperature. In order to strengthen the reducing agent, it reacts with sulfur dioxide to form sodium hydrogen sulfite, and reacts with a strong acid to form a corresponding salt.
