SODIUM HYPOSULFITE Chemical compatibility with O-rings, rubbers, & plastics

Sodium Hyposulfite, also known as sodium thiosulfate (Na2S2O3), is a white, crystalline compound used in various industrial and chemical applications as a reducing agent, dechlorinating agent, and analytical reagent. In the photographic industry, Sodium Hyposulfite is employed as a fixing agent to dissolve unreacted silver halides from photographic films and papers, providing stability and preventing fading of images. It is also used in water treatment to neutralize chlorine and reduce chlorine-related disinfection by-products. In the chemical industry, Sodium Hyposulfite is used as a reducing agent in the synthesis of various organic compounds and as a reagent in analytical chemistry for the titration of iodine. Proper handling and storage of Sodium Hyposulfite are essential to maintain its quality and prevent moisture absorption. It is generally considered safe for use, although proper safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are essential to prevent irritation and other health hazards. Its versatility and effectiveness make Sodium Hyposulfite a valuable chemical in numerous applications.
