You can describe the redox reaction shown by the equation in terms of oxygen loss or gain.

Using **half-equation** an equation that shows one-half of a redox reaction, you can describe any redox reaction in terms of electron transfer.

NOTEYou can write an oxidation (electron loss) half equation in any of the following ways:

*The second option is the standard way of showing electron loss.*
