# Half Equations

Ionic equations (redox equations) are very important and follow on from looking at oxidation states. These equations are formed from the combination of two half-equations i.e. equations involving either oxidation or reduction. Forming half-equations is often the most difficult part as getting the ionic equation simply involves cancelling electrons. Therefore, we look at how to form simple and complicated half equations by adding H+ ions, water and electrons.
