WebJul 20, 2024 · Redox couples are analogous to conjugate acid-base pairs and behave in much the same way. The stronger an oxidizing agent, the weaker the corresponding reducing agent, and the stronger a reducing agent, the weaker the corresponding oxidizing agent. Thus the strong oxidizing agent F 2 produces the weak reducing agent F –. Redox couples are analogous to conjugate acid-base pairs and behave in much the same way.
