GCSE Chemistry - Oxidation and Reduction - Redox Reactions #39 (Higher Tier)

The video tutorial covers redox reactions, where oxidation and reduction occur simultaneously. It explains oxidation as the gain of oxygen or loss of electrons, and reduction as the loss of oxygen or gain of electrons, using the mnemonic 'oil rig'. Examples include magnesium reacting with acid and displacement reactions like calcium displacing iron. The tutorial also covers writing ionic and half equations, focusing on electron transfer and charge balance.
