Electrochemistry: Early History Luigi Galvani (1737-1798) In the mid-1780s, anatomist Luigi Galvani (Bologna, Italy) was studying the effects of atmospheric electrical discharge. One day, in his garden, he fastened brass hooks between the spinal cord of a dissected frog and an iron railing. To his amazement the frog's legs began twitching wildly, not only when lightning flashed, but also when the sky was calm. Galvani interpreted his results in terms of animal electricity (incorrect). Galvani proclaimed that the muscle retained a nerveo-electrical fluid similar to that of an electric eel. While his papers on the subject ignited research among scientists of Europe, the most significant consequence of Galvani's discovery was the concept of Galvanism which refers to the production of electrical current from the contact of two metals in a moist environment. Shortly before he died, Galvani was dismissed from his professorship at the University of Bologna, because he refused to swear allegiance to Napoleon's Republic. Alessandro Giuseppe Volta (1745-1827) Volta was born in Como, Italy (near Milan). In 1774, he began his first academic position as principal of the state Gymnasium in Como. In 1777, he was appointed Professor of Physics at the University of Pavia. Here he began to repeat Galvani's famous experiments with decapitated frogs. He observed that Galvani had connected brass hooks between the frog's spinal cord and an iron railing. According to Volta's interpretation, the muscle twitches were induced by current flowing between two dissimilar metals connected by the moist flesh of the frog's leg. This led him to develop the first device which demonstrated chemical production of electric current. In 1799, Volta arranged a vertical pile of metal discs (zinc with copper or silver) and separated them from each other with paperboard discs that had been soaked in saline solution. This stack became known as the voltaic pile and was the first electric battery.

ELECTROCHEMISTRY Electrochemistry is the area of chemistry dealing with the interconversion of electrical energy and chemical energy. There are many applications of this in every day life. Batteries, control of corrosion, metallurgy and electrolysis are just a few examples of the applications of electrochemistry. This handout will look at the basic principles of electrochemistry and show some of its applications. Electrochemistry always involves an oxidation-reduction process. Recall that oxidation involves the loss of electrons by a substance and that reduction involves the gain of electrons by a substance. You can’t have one process without the other. The substance that is reduced is the oxidizing agent. This makes sense, because how you define an oxidizing agent – a compound that is able to oxidize another substance by removing electrons from that substance. Since the oxidizing agent is gaining the electrons that it pulls off the substance it is oxidizing, the oxidizing agent becomes reduced during the process. Similarly, the substance that is oxidized is the reducing agent.

Your browser does not support script Electrochemistry Back Home Next Readings for this section Petrucci: Section 3-1, Chapter 20; Introduction Electrochemistry is the study of interchange of chemical and electrical energy. Oxidation/Reduction involves the exchange of electrons from one chemical species to another. Normally, this is done when the two chemicals contact each other in the activated complex (when two species bump into each other in solution for example). We are interested in separating the chemical species such that the electrons transfer via an external circuit. That way, we can measure the electrochemical effects. To properly understand the connection between the redox reaction and the electricity, we should balance the overall redox reaction using a half-reaction method such as the one described in the previous section of these notes. We can set up the physical reaction vessel such that the chemicals from one half reaction are separated from those of the second half reaction. For reaction to occur, we still need to connect the solutions to complete the circuit. This is done by attaching wires between electrodes in the two half cells and by connecting the solutions of the two half cells via a salt bridge or by some other device such as a semi-permeable membrane. In general, such a cell is called an electrochemical cell. These cells could be used in one of two types of situations:

MM_preloadImages('images/ch1lt.jpg'); CHAPTER 3 ELECTROCHEMISTRY The Nernst Equation The Nernst equation describes the fundamental relationship between the potential applied to an electrode and the concentration of the redox species at the electrode surface. If an electrode is at equilibrium with the solution in which it is immersed, the electrode will have a potential, invariant with time, which is thermodynamically related to the composition of the solution. In solution, species O is capable of being reduced to R at the electrode by the following reversible electrochemical reaction. O + ne R The Nernst equation relates the potential, E, which is applied to the electrode and the concentrations of species O and R at the electrode surface: E = E log [O] n [R] where E = potential applied to electrode E = formal reduction potential of the couple vs. reference electrode n = number of electrons [O] = surface concentration of species O [R] = surface concentration of species R.
