Electrochemistry From Wikipedia, the free encyclopedia Jump to: navigation search English chemists John Daniell left ) and Michael Faraday right ), both credited to be founders of electrochemistry as known today. Electrochemistry is a branch of chemistry that studies chemical reactions which take place at the interface of an electron conductor (the electrode composed of a metal or a semiconductor , including graphite ) and an ionic conductor (the electrolyte ) and which involve electron transfer between the electrode and the electrolyte. If a chemical reaction is caused by an external voltage , as in electrolysis , or if a voltage is caused by a chemical reaction, as in a battery , it is an electrochemical reaction. Chemical reactions where electrons are transferred between atoms are called oxidation/reduction (redox) reactions. In general, electrochemistry deals with situations where oxidation and reduction reactions are separated in space, connected by an external electric circuit.

EXPERIMENTS IN ELECTROCHEMISTRY by Giorgio Carboni, January 1998 Translated by G.L. Stuart CONTENTS INTRODUCTION CONDUCTORS BATTERIES THE LEMON BATTERY ... CONCLUSION INTRODUCTION In 1791 Luigi Galvani discovered electrical activity in the nerves of the frogs that he was dissecting. He thought that electricity was of animal origin and could be found only in living tissues. A few years later, in 1800 Alessandro Volta discovered that electricity could be produced through inorganic means. In fact, by using small sheets of copper and zinc and cloth spacers soaked in an acid solution, he built a battery - the first apparatus capable of producing electricity. Naysayers were quick to predict that electricity would never serve a useful purpose. Obviously they were very wrong. Electricity has a central role in our lives and to this day Electrochemistry is a standard course of study. While listening to lessons on Electrochemistry, many students may wonder why it was ever invented, if it was really ever necessary to invent it and if the world would be better off without it. With the small experiments that follow, we hope to make peace between these students and the study of Electrochemistry. These fun and simple experiments can teach the fundamental concepts of Electrochemistry without asking much of the student. As you will see, many of these demonstrations are easily adapted to various configurations and each can be done independently or as part of the full curriculum. POROUS VASE - An actual porous vase made for the purpose may be difficult to acquire. It is used to prevent the quick mixing of various solutions, while permitting the exchange of ions. For our purposes you can adapt a terracotta pot of the type used in gardening simply by plugging the hole in the bottom with molten wax and allowing it to cool. Another even more economical answer lies in constructing a barrier of paper. As shown in figure 4, roll the paper to form a cylinder and glue it in place on the bottom of the main container using a silicone adhesive such that liquids cannot pass between the two areas defined by the paper. A barrier of just one sheet would be too permeable, therefore use at least three layers of paper when building this device.

Table: Standard State Reduction Potentials Electrical Work From Spontaneous Oxidation-Reduction Reactions T he following rule can be used to predict whether an oxidation-reduction reaction should occur. Oxidation-reduction reactions should occur when they convert the stronger of a pair of oxidizing agents and the stronger of a pair of reducing agents into a weaker oxidizing agent and a weaker reducing agent. Practice Problem 1: Predict whether zinc metal should dissolve in acid. Click here to check your answer to Practice Problem 1 We can test this prediction by adding a few chunks of mossy zinc to a beaker of concentrated hydrochloric acid. Within a few minutes, the zinc metal dissolves, and significant amounts of hydrogen gas are liberated. The reaction in Practice Problem 1 has some of the characteristic features of oxidation-reduction reactions.

The Plastic Hydrogen Bomb uses electricity to break apart water molecules into hydrogen and oxygen. Then it uses a spark of electricity to explosively recombine the gases into high pressure steam, which propels a stream of water high into the air. The construction is a little more difficult than the other toys in this book, but the skills learned by building this toy can be put to good use building many other devices and works of art.

Your browser does not support script 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:
