Danger
Inflammable:Sodium dithionite is a first-class flammable item when wet according to national standards. It will react violently when it comes into contact with water, producing flammable gases such as hydrogen sulfide and sulfur dioxide, and releasing a large amount of heat. The reaction equation is: 2Na2S2O4+2H2O+O2=4NaHSO3, and the products further react to produce hydrogen sulfide and sulfur dioxide. Sodium dithionite has an intermediate valence state of sulfur, and its chemical properties are unstable. It shows strong reducing properties. Lorsqu'il rencontre de forts acides oxydants, tels que l'acide sulfurique, l'acide perchlorique, l'acide nitrique, l'acide phosphorique et d'autres acides forts, les deux subiront une réaction redox, et la réaction est violente, libérant une grande quantité de chaleur et de substances toxiques. Its reaction equation is: 2Na2S2O4+4HCl=2H2S2O4+4NaCl
