Electrochemistry

A very important (and often entertaining) class of reactions involves the transfer of electrons between reactants. //Electrochemistry// describes these "redox" reactions in more detail, and in this unit you will learn how to harness a reaction's Gibbs free energy by making a battery that will produce an electric current in a circuit. You will then learn how to essentially do the opposite: use an electric current to drive a thermodynamically-unfavorable reaction forward. At last, you'll finally learn how you COULD extract the much-coveted sodium metal from salt!
