SODIUM SULFITE belongs to the alkali metal sulfites, a subclass of alkali metal oxoanionic compounds within the inorganic compounds. This compound serves a wide variety of industrial roles and uses, including applications as a preservative, flux agent, fragrance, filler, and dye. It is further utilized as a pH regulating agent, antioxidant, food preservative, oxidizing agent, and corrosion inhibitor. In biological contexts, it acts as a reducing agent (PMC5013196). Additionally, it is used industrially for hair waving or straightening and as processing aids not otherwise specified. Sodium sulfite is found in or released from 24 recorded sources. In the category of electrical and electronic equipment, it is associated with antennas, amplifiers, communication cables or conductors, electric switches, and discharge lamps, among five others. Within food, food processing and cookware, it is linked to the processing of fish, the preparation of vinegar, the preparation of wort, fermentation processes for beer, and the preparation of wine or sparkling wine, among two others. It is also found in building and construction materials such as roofs, ceilings, fencing, and tents or canopies. Furthermore, it is present in household cleaning and consumer products, including tobacco smoke filters, cigar cigarettes, and bleaching agents.
