| Also Known As | Electron gain, Electroreduction, Hydrogenation (applied) |
What is Reduction?
A process involving the gain of electrons, decrease in oxidation state, or loss of oxygen. In redox reactions, reduction always accompanies oxidation. The species gaining electrons is called the oxidizing agent. Reduction half-reactions occur at the cathode in electrochemical cells.
