Basic Solution:

Separate the reaction into two half-reactions.

Balance each half-reaction separately:

  1. Balance atoms other than O & H by inspection.

  2. Balance O by adding H2O to the opposite side.

  3. Balance H by addding H+ as appropriate.

  4. Balance the charge by adding electrons (e-) - add to same side as excess of positive charge, or opposite side if excess negative charge.

  5. Balance the charges of the two half-reactions by multiplying appropriately.
