RedOx Chemistry

RedOx Chemistry. OK, I balanced the frigging equation, so what?. An example of an Electrochemical Reaction. Oxidation half-reaction: Fe 2+ ? Fe 3+ + 1 e - Reduction half-reaction: Sn 4+ + 2 e- ? Sn 2+ Net: 2 Fe 2+ + Sn 4+ ? 2 Fe 3+ + Sn 2+ So frigging what? Well a couple things:.

Voltaic Cells

Voltaic Cells. Chapter 20. Voltaic Cells. In spontaneous oxidation-reduction (redox) reactions, electrons are transferred and energy is released. Also known as electrochemical cells. Voltaic Cells. We can use that energy to do work if we make the electrons flow through an external device.
