Balancing Half Reactions in acidic solution

Step 1 Write separate equations for the Oxidation-reduction half reactions.

Step 2 A. Balance all of the elements except hydrogen and oxygen B. Balance oxygen using H2O C. Balance hydrogen using H+1 D. Balance the charge using electrons.

Step 3 If necessary, multiply one or both balanced half-reactions by an integer to equalize the number of electrons transferred in the two half-reactions.

Step 4 Add the half-reactions together, and cancel identical species.

Step 5 Check that the elements and charges are balanced.
