This product exists as white crystals or powder. It is readily soluble in water, very slightly soluble in ethanol, and almost insoluble in ether.
Uses
1.Metallurgical Industry: In the metallurgical industry, sodium sulfite mainly serves as an inhibitor. During the mineral - dressing process, it can effectively separate minerals and enhance the efficiency of ore dressing. For instance, Luo Chaoyan et al. studied that a mixed solution of zinc sulfate and sodium sulfite can inhibit the flotation of marmatite in lead - zinc ore dressing, thereby improving the grade and recovery rate of lead concentrate. Additionally, sodium sulfite can also be used in processes such as metal cleaning and electroplating.
2.Pharmaceutical Industry: In the pharmaceutical industry, sodium sulfite is mainly used as a raw material for the synthesis of pharmaceutical ingredients. For example, in the production of taurine, sodium sulfite reacts with ethanolamine, sulfuric acid and other raw materials. Through a series of steps, taurine can be obtained. Taurine is an important amino acid with various physiological functions and is commonly used in the production of health supplements and pharmaceuticals.
3.Water Treatment: In the field of water treatment, sodium sulfite is mainly used for deoxygenation of boiler feed water and treatment of chromium - containing wastewater.
