1. Separate the process into half reactions.
2. Balance each half reaction separately.
3. Adjust coefficients to balance all atoms except H and O.
4. Add one H2O for each O atom needed to the side deficient in O.
5. In acidic solution, add one H+ for each H needed to the side deficient in H. In basic solution, add one H[sub]2[sub]O for each H atom needed to the side deficient in H and an equal number of OH to the opposite side.
6. Add a sufficient number of electrons to the side deficient in electrons to balance the charge.
7. Multiply each half reaction by an appropriate number so as to balance the electron gain and loss in the overall reaction.
8. Add the half reactions together and eliminate duplication on the left and right.
