Add the two halfreactions together and balance the final equation by inspection. The number of electrons on both sides must cancel. 6e+ 14H + + Cr 2 O 7 22Cr 3+ + 7H 2 O 6Fe 2+ 6Fe 3+ + 6eOxidation: Reduction: 14H + + Cr 2 O 7 2+ 6Fe 2+ 6Fe 3+ + 2Cr 3+ + 7H 2 O 8. Verify that the number of atoms and the charges are balanced . 14x1 2 + 6 x 2 = 24 = 6 x 3 + 2 x 3 9. For reactions in basic solutions, add OHto both sides of the equation for every H + that appears in the final equation....
