Grade 12 chemistry - Oxidation-Reduction Reactions

Oxidation

The process in which one or more electrons is lost by a chemical entity

Reduction

The process in which one or more electrons is gained by a chemical entity

Oxidation-reduction (redox) reaction

The reaction in which one or more electrons are transferred between chemical entities

Half-reaction equation

The part of an oxidation—reduction reaction equation representing either the oxidation reaction or the reduction reaction

Oxidation number

A number used to keep track of electrons in oxidation-reduction reactions according to certain rules; also known as oxidation state

Oxidizing agent

The reactant that is reduced (gains electrons from another substance) during an oxidation-reduction reaction

Reducing agent

The reactant that is oxidized (loses electrons to another substance) during an oxidation-reduction reaction

Redox table

A table listing standard reduction potentials of common oxidizing agents and reducing agents in order from strongest to weakest; standard reduction potentials table
