Achievement standard 91167

Demonstrate understanding of oxidation-reduction

Internal, 3 credits

Involves describing, identifying, naming, giving an account of oxidation-reduction and describing oxidation-reduction reactions.

Redox reactions involve the transfer of electrons from one substance to another.

Iron rusting is an example of a redox reaction.
As is Silver nitrate + copper --> copper nitrate + silver
