Consider the following equation in aqueous solution: Cr20,2-(aq) + S203²-(aq) → Cr³*(aq) + S4062-(aq) The oxidation half-reaction is 2 S2032- (aq) → S4O6²- (aq) + 2 e- and the reduction half-reaction is Cr20,2-(aq) + 14 H*(aq) + 6 e- → 2 Cr** (aq) + 7 H20(1). Write the balanced equation for the overall reaction in acidic solution.
