Identify the oxidation and reduction half-reactions
Assign oxidation numbers to all atoms that change
Balance atoms other than O and H in each half-reaction
Balance oxygen atoms by adding H2O
Balance hydrogen atoms by adding H+ in acidic solution
Balance hydrogen atoms by adding OH- and H2O in basic solution
Balance charge by adding electrons
Multiply half-reactions to equalize electrons
Add the half-reactions together
Cancel electrons and any species appearing on both sides
Verify that atoms and total charge are balanced
