Chemistry - Redox Reactions - Balancing redox equations - Half-Reaction Method

Step-by-step walkthrough of balancing redox equations using the half-reaction method. Example: MnO₄⁻ + Fe²⁺ → Mn²⁺ + Fe³⁺ (in acidic solution). Step 1: 'SPLIT into half-reactions. Oxidation: Fe²⁺ → Fe³⁺. Reduction: MnO₄⁻ → Mn²⁺.' Step 2: 'BALANCE atoms other than O and H. Fe²⁺ → Fe³⁺ ✓. MnO₄⁻ → Mn²⁺
