In photography, unexposed silver bromide is removed from film by soaking the film in a solution of sodium thiosulfate, Na2S2O3. Silver ion forms a soluble complex with thiosulfate ion, S2O32-, that has the formula Ag(S2O3)23-, and formation of the complex causes the AgBr in the film to dissolve. The Ag(S2O3)23- complex has Kform= 2.0 x 1013. How many grams of AgBr (Ksp= 5.4 x 10-13) will dissolve in 126 mL of 1.27 M Na2S2O3 solution?
