This MCAT podcast covers electrochemistry. First, I give an intro to electrochemical cells where I talk about galvanic vs electrolytic cells, concentration cells, the structure of an electrochemical cell, reduction/oxidation, directionality of electron flow, and a mnemonic I use to keep it all straight. Next, I talk about some thermochemistry regarding electrochemical cells, like Gibbs free energy and the nerds equation (as it applies to a concentration cell). Last, I discuss several applications of electrochemistry including electroplating.
