Redox Reactions

Explain the term oxidation state (number)

A measure of the number of electrons an atom uses to bond with atoms of a different element.

Explain the term oxidation

The loss of electrons, or an increase in oxidation number.

Explain the term oxidising agent

A reagent that oxidises another species by accepting electrons (and is itself reduced).

Explain the term reduction

The gain of electrons, or a decrease in oxidation number.

Explain the term reducing agent

A reagent that reduces another species by donating electrons (and is itself oxidised).

Explain the term redox

A reaction in which both oxidation and reduction occur simultaneously.

Explain the term disproportionation

A reaction where the same element is simultaneously oxidised and reduced.

Explain the term displacement reaction

A redox reaction where a more reactive halogen oxidises the halide ion of a less reactive halogen.
