Using the half-equation method, balance the following redox half-equations in an acidic solution and state if each half-equation is either oxidation or reduction. To balance a half-equation with polyatomic ions: Step 1: Balance atoms other than oxygen and hydrogen Step 2: Balance oxygen by adding water (H20) Step 3: Balance hydrogen by adding H*(aq) Step 4: Balance the charge by adding e to the more positive side Half-equation Oxidation or Reduction?
