2. Balance the following reaction that occurs in acid, using the half-reaction method. I-1(aq) + CrO4-1(aq) --> I2(s) + Cr+3(aq) When this reaction is balanced, there will be (?) H+(aq) and (?) H2O(l) in the final balanced equation. (Enter numbers without the plus sign.)
In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods: the half-reaction method or the oxidation number method. The half-reaction method balances the electrons lost in the oxidation half-reaction with the electrons gained in the reduction half-reaction. In either method H2O(l), OH−(aq), and H+(aq) may be added to complete the mass balance. Which...
