Explain the displacement of metals from solution in terms of transfer of electrons
- Oxidation: Loss of electrons.
- Reduction: Gain of electrons.
- Redox (Reduction-Oxidation) Reaction: A reaction in which both oxidation and reduction occur, and hence transfer of electrons occurs.
- Displacement Reaction: A reaction in which a more reactive metal converts the ion of a less reactive metal to the neutral atom.
- Displacement reactions are redox reactions, with the more reactive metal being oxidised, and the ion of the less reactive metal being reduced.
- In displacement reactions, electrons are transferred from the more reactive metal to the ion of the less reactive metal.
