CAS :Sodium sulfite is a salt that is used as a food additive and in the chemical industry. It has been used to study the toxicity of sodium salts and their effect on the cardiovascular system. Sodium sulfite is also used as a diagnostic agent in ethylene diamine tests, which are used to detect fatty acid levels in blood serum. The process optimization of sodium citrate production has been studied using sodium sulfite heptahydrate. Hydrochloric acid can be used to remove sulfur dioxide from sodium sulfite heptahydrate, producing anhydrous sodium sulfate. Sodium carbonate can be produced by adding water to anhydrous sodium sulfate, forming a solution of hydrogen ions and hydroxide ions. Sodium carbonate can also be produced through the reaction of anhydrous sodium with carbon dioxide gas or calcium oxide. Hydrogen bonds between molecules may be disrupted by adding hydrochloric acid to anhydrous sodium sulfate, leading to the formation of diphenyl etherFormule :Na2SO3•(H2O)xDegré de pureté :(%) Min. 98%Couleur et forme :PowderMasse moléculaire :126.04 g/molSodium Sulphite Anhydrous extrapure AR, ACS, ExiPlus, Multi-Compendial, 98%
