Chemistry - Redox Reactions - Introduction to oxidation and reduction - OIL RIG Memory Game
8 matching pairs to teach the OIL RIG mnemonic for Grade 10. Pairs: 1) 'OIL' → 'Oxidation Is Loss (of electrons)'. 2) 'RIG' → 'Reduction Is Gain (of electrons)'. 3) 'Fe → Fe²⁺ + 2e⁻' → 'OXIDATION (Fe lost electrons)'. 4) 'Cu²⁺ + 2e⁻ → Cu' → 'REDUCTION (Cu²⁺ gained electrons)'. 5) 'Oxidizing agent' →
