Explain ions can form complexes with the thiosulfate ion

Reference no: EM13493582

We sometimes use complex formation to make relatively insoluble salts more soluble. For instance, AgCl(s) has Ksp=1.6x10^-10. Silver ions can form complexes with the thiosulfate ion (S2O3^2-), however: Ag^+ (aq) + 2 S2O3 ^2- (aq) <---> [Ag(S2O3)2]^3- (aq) Kf=1.7 x 10^13. Using the information, calculate K for the reaction AgCl(s) + 2 S2O3 ^2- (aq) <---> [Ag(S2O3)2]^3- (aq_ + Cl^- (aq).
