Redox reactions and electrochemistry

Oxidation and reduction reactions power your phone and make it possible for your body to use the oxygen you inhale. We will learn about oxidation states (numbers), oxidation-reduction (redox) reactions, galvanic/voltaic cells, electrolytic cells, cell potentials, and how electrochemistry is related to thermodynamics and equilibrium.

Oxidation-reduction reactions

Oxidation and reduction are powerful ideas for thinking about how charge is transferred within a reaction. As we'll see, it is something of a hypothetical, but it is, nonetheless, very useful.
