Electrochemistry From Wikipedia, the free encyclopedia. Electrochemistry is the science of the reactions that can take place at the interface of an electronic conductor (the electrode , which can be a metal or a semiconductor including graphite ) and an ionic conductor (the electrolyte If a chemical reaction is caused by an external voltage , or if a voltage is caused by a chemical reaction, as in a Battery (electricity) , it is an electrochemical reaction. In general, electrochemistry deals with situations where an oxidation and a reduction reaction is separated in space. The direct charge transfer from one molecule to another is not the topic of electrochemistry. Contents Oxidation and Reduction Spontaneity See also External links ... edit Oxidation and Reduction The elements involved in an electrochemical reaction are characterized by the number of electrons each has. The oxidation state of an ion is the number of electrons it has accepted or donated compared to its neutral state (which is defined as having an oxidation state of 0). If an atom or ion donates an electron in a reaction its oxidation state is increased, if an element accepts an electron its oxidation state is decreased. For example when sodium reacts with chlorine, sodium donates one electron and gains an oxidation state of +1. Chlorine accepts the electron and gains an oxidation state of −1. The sign of the oxidation state (positive/negative) actually corresponds to the value of each ion's electronic charge. The attraction of the differently charged sodium and chlorine ions is the reason they then form an

AD 1806 Humphry Davy Electrochemistry Humphry Davy (1778-1829), an English chemist, proved that it was not using two different metals that made the Voltaic Pile work. The electricity was actually caused by the chemical reaction caused by the cloth soaked in brine that Volta had used to increase conductivity. Davy was able to create an electric current from the same metal in two different fluids with the metal in each fluid touching. Among his early experiments, he used the Voltaic Pile to decompose water into hydrogen and oxygen. In fact he used this method to decompose several compounds and in the process discovered several new elements.

The Plastic Hydrogen Bomb It sounds like the perfect terrorist weapon , but it is a toy that teaches the principles of electrochemistry. It's also a high-tech squirt gun. 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.

Computational Electrochemistry 2004 Computational Electrochemistry A 3-day workshop on the application of atomistic computer simulation to interfacial electrochemistry will be held from September 26 to September 29, 2004, on Santorini island, Greece. Modern Electrochemisty, specifically interfacial electrochemistry, is a complex interdisciplinary field which will benefit tremendously from increasing interaction with theoretical chemistry. The purpose of this workshop will be to bring together experts in several fields of theoretical chemistry and physics, such as quantum chemistry, density functional theory, Monte Carlo, classical and ab initio molecular dynamics simulations, with experimental electrochemists having a broad overview of the field. The main focus will be on a thorough discussion of experimental and theoretical methods to investigate adsorbate dynamics and chemical processes at liquid/solid interfaces, on and in oxides and at grain boundaries. The format of the meeting should facilitate discussions between the two groups. There will be only invited lectures, posters, and a round-table discussion. Electrochemists are supposed to identify the most important experimental problems, with a special emphasis on the atomic or molecular transport through and nearby interfaces. Computational chemists, in their turn, will discuss adequate techniques to address these problems. We encourage speakers to make their presentations sufficiently general and introductory so that discussions between the two groups are maximally fruitful.

This knowledge is a prerequisite for studying e.g. the fundamentals of extractive metallurgy. But as the discussion of the basic concepts is very general and fundamental also other courses in material science (corrosion, phase transformations, ...) should take advantage of this knowledge.
