INTERACTIVE EXAMPLE Balancing Oxidation-Reduction Reactions (Basic) Balance the following oxidation-reduction reaction as if it were to occur in a basic solution. I(aq) + Clo (aq) - 13 (aq) + cr(aq) HOW DO WE GET THERE? In the reduction half-reaction, there are 2 electrons on the left-hand side, and there are 2 electrons on the right-hand side of the oxidation half- reaction. Therefore, the electrons balance overall. What is the complete reaction? O3r (aq) – I3 (aq) O2 H*(aq) + Clo (aq) - Cl (aq) + H20(I) I(aq) + Clo (aq) – I3 (aq) + Cl (aq) 3r(aq) + Clo(aq) - 13 (aq) + CIF(aq) 2 H*(aq) + Clo-(aq) + 31(aq) – 13 (aq) + Cl (aq) + H20(1) Check Next (6-of 8)
