Interactive Example: an online interactive tutorial to show you step-by-step how to apply the steps described below.
Rules Review: an online interactive pop quiz to test your memory of the order of the steps.

Step 1: Separate in half reactions.

Step 2: In each half reaction, balance all elements except O & H.

Step 3: Balance O by adding H₂O.

Step 4: Balance H by adding H⁺.

Step 5: Balance charges by adding e^-.

Step 6: Multiply all coefficients in 1 or both half reactions by an integer to get the number of e^- in the two half reactions equal.

Step 7: Add the 2 half reactions together & cancel out any species that appear on both sides of net reaction.

Step 8: Check that charges and atoms are balanced.
