WebApr 8, 2024 · Note: Reducing agent loses electrons and is oxidized while an oxidizing agent gains electrons and is reduced. This is the basis of a Redox reaction. In a Redox reaction, both oxidation and reduction occurs in the same chemical reaction. The heating of ammonium dichromate is a prime example of one such redox reaction. WebOxidation and reduction (redox) reactions are opposing reactions that occur simultaneously. Figure 4.9 This is the balanced equation to show how ethanol is oxidized to acetic acid.
