How do you write half equations in chemistry?
Edit Article. A half equation is a chemical equation that shows how one species - either the oxidising agent or the reducing agent - behaves in a redox reaction. If you add two half equations together, you get a redox equation. 1. Identify the species for which you are writing the equation.
How to write redox reactions and half reactions?
