Solution: Solutions of sodium thiosulfate are used to dissolve unexposed AgBr (K sp = 5.0 X 10 -13) in the developing process for blackand- white film. What mass of AgBr can dissolve in 1.00 L of 0.500 M Na2S2O

Problem

Solutions of sodium thiosulfate are used to dissolve unexposed AgBr (K sp = 5.0 X 10 -13) in the developing process for blackand- white film. What mass of AgBr can dissolve in 1.00 L of 0.500 M Na2S2O3? Ag+ reacts with S2O32- to form a complex ion:

Ag+(aq) + 2S2O32-(aq) ⇌ Ag(S2O3)23-(aq)     

        K = 2.9 X 10 13
