WebSilver ion, Ag+, forms a soluble complex with the thiosulfate ion, S2O3-2, that has a formula of Ag (S2O3)2-3, and the formation of the complex causes the AgBr in the film to dissolve. The formation of the complex has a Kf of 2.0 x 10^13 while the Ksp of AgBr is 5.0 x 10^-13. WebThis is written as Ag+ + e- → Ag. As electrons are gained, the silver ion is reduced. The strongest oxidation half-reaction that could occur is the oxidation of the sulfite ion (S2O3^2-) to the sulfate ion (SO4^2-). This is written as S2O3^2- → SO4^2- + 2e-. As electrons are lost, the sulfite ion is oxidized. WebThiosulfate ion O3S2-2 - PubChem Apologies, we are having some trouble retrieving data from our servers...
