GCSE Chemistry – Redox Reactions – Displacement Reactions | Ionic Equations | Half Equations

⭐️ Check out our website https://www.cognito.org/ ⭐️

*** WHAT’S COVERED ***
1. Redox Reactions (Reduction-Oxidation)
* Defining oxidation and reduction in terms of oxygen gain and loss.
* Defining oxidation and reduction in terms of electron transfer (using the OIL RIG mnemonic).
* Understanding that oxidation and reduction occur simultaneously in redox reactions.
2. Displacement Reactions
* Explaining how a more reactive metal displaces a less reactive one from a solution.
* Identifying displacement reactions as examples of redox reactions.
3. Ionic and Half Equations
* Identifying and removing spectator ions to create ionic equations.
* Writing individual half equations to show the oxidation and reduction processes separately.
* How to balance charges in half equations by adding electrons.
