Physical and chemical properties Calcium sulfite, chemical formula CaSO3·2H2O. Molecular weight 156.17. Colorless crystal or white powder. Specific gravity 1.595. Slightly soluble in water and alcohol, soluble in sulfur dioxide aqueous solution. When encountering acid, it decomposes to release sulfur dioxide. It is slowly oxidized into calcium sulfate in the air. It loses crystal water at 100℃ and decomposes at 650℃. It is obtained by the action of sulfurous acid and calcium carbonate or by passing sulfur dioxide into milk of lime. Used as bleach, bactericide, food preservative, etc. The application of calcium sulfite can remove residual chlorine in water, including combined residual chlorine NH2ChemicalbookCL, NHCL2 and NCL3 and free residual chlorine CLO-, HOCL, CL2, etc. Compared with traditional activated carbon, the chlorine removal effect is more efficient, safe and durable. It has the advantages of high temperature and no breeding of bacteria. It is widely used in various water types to remove residual chlorine in Japan, South Korea, Malaysia, Taiwan and other Southeast Asian countries and regions. Usage: It is used as an analytical reagent, and is also used in the textile, paper and sugar industries. It is also used in calcium plastic materials. It is also used as a bleaching and dechlorinating agent for cellulose products, food preservatives, fermentation bactericides, etc. .
