An oxidising agent is a chemical species that causes the other reactant in a redox reaction to be oxidised, and it is always reduced in the process. Redox reactions can therefore be used to generate electrical current. 12. As usual, oxidation and reduction occur together. Redox Titration Curves. The overall reaction equation is obtained by combining the separate half equations Some important applications are as follows: 1. Because the term oxidation-reduction is a bit cumbersome, we usually call these reactions redox reactions.
