In an electrochemical reaction, the chemical species are related by kinetic equations, both chemical... and electrochemical (the rate of which may involve variables such as the applied voltage)... The 'movement' of the species due to Diffusion, flow etc. (known as 'Mass Transport') may also be described mathematically by a partial differential equation for each species. These equations cannot be solved analytically except for extremely simple cases, but they can be solved numerically (using a finite difference method - where the cell is covered in a mesh of points so that the derivatives can be approximated as differences between points). By applying boundary conditions at the edges of the grid, the resulting set of simultaneous equations can be solved by an algorithm such as the Strongly Implicit Procedure. The result of solving all the equations with a computer is a concentration profile for each species - describing the spatial concentration distribution of that species within the electrochemical cell. The concentration profile above shows a microband electrode at steady-state in a channel flow-cell. The colour scale represents reactant concentration (pink = bulk concentration, blue = zero concentration)

Southampton Electrochemistry Summer Schools Electrochemistry, Electrochemical Engineering and Electrochemical Technology Sponsors: Electrosynthesis Electrocell Europe Electrochemistry, Electrochemical Engineering and Electrochemical Technology: June - 4 July 2008 Electrochemistry, Electrochemical Engineering and Electrochemical Technology is a one week, residential course designed to introduce the practical steps essential to implement electrochemical technology on a commercial scale. It is intended to compliment the course Instrumental Methods in Electrochemistry , run almost annually in Southampton since 1969. Indeed, we hope that those who found Instrumental Methods in Electrochemistry useful will return to Southampton to attend the new course. In the Southampton tradition, Electrochemistry, Electrochemical Engineering and Electrochemical Technology will consist of both lectures (with full written supporting material) and hands-on practical sessions. The early lectures will cover core material such as: applications of electrochemistry fundamental electrochemistry voltammetry steps to move from the laboratory to commercial exploitation current and potential distribution electrode materials and membranes cell design The final three lecture sessions will address specific topics in electrochemical technology, especially examples of applications. In 2008 these topics will be:

The principal objective of research in this group is the elucidation of the mechanisms of complex, multi-step electrode reactions of organic and organometallic compounds. The results of this research are relevant not only in the areas of organic and inorganic chemistry, but also find applications in chemical analysis, electroorganic synthesis, pollution control, electrocatalysis, batteries and fuels cells. A full understanding of an electrode reactions must include a complete description of its component steps. Thus, our work includes studies of the factors controlling the rates of simple electron-transfer reactions occurring at electrode surfaces as well as the electron-transfer reactions in solution near the electrode that involve the various species in the overall mechanism (reactants, intermediates, products). Other component reactions are of a more chemical nature. They may be as simple as an isomerization or conformational change of the reactant or an intermediate. However, bonds may also be formed (dimerization, protonation) or broken (loss of an atom or functional group) and these steps combine with the electron-transfer reactions to make up the overall process. An important type of reaction is bond cleavage associated with electron transfer to or from the reactant. Most such reactions are two-step processes in which an intermediate radical anion is formed followed by expulsion of a leaving group. However, others appear to be concerted processes (dissociative electron-transfer reactions) in which both steps occur together and no intermediate radical ion exists. Part of our research is directed toward discovering new examples of the rarer type, dissociative electron transfers.

Welcome to the Hot Wire Electrochemistry Website! Study electrochemistry Accelerate slow reactions Intensify mass transport Enhance selectivity Investigate corrosion ... by means of heated electrodes On these pages, we would like to provide you with some essential information about the electrochemistry at directly heated electrodes, also known as hot-wire electrochemistry This novel technique allows to vary arbitrarily the temperature of an electrode when an electrochemical experiment is running. One can bring about an efficient stirring effect, but on the other hand one can work without any convection and rise the temperature far above the boiling point. The uncommon behaviour of heated microelectrodes allows to design novel chemical sensors with amazing properties. Such sensors are small and cheap. They can be utilized in many analytical applications and they can operate smoothly at remote places. At present, electrochemistry at directly heated microelectrodes is an advanced technology with a well investigated background. Measurements can be performed easily with

Building a plastic hydrogen bomb. Electromachining, electroetching, and electroplating. Building your own solar battery. A flat panel solar battery. Make a solar cell in your kitchen A solar cell is a device for converting energy from the sun into electricity. The high-efficiency solar cells you can buy at Radio Shack and other stores are made from highly processed silicon, and require huge factories, high temperatures, vacuum equipment, and lots of money. If we are willing to sacrifice efficiency for the ability to make our own solar cells in the kitchen out of materials from the neighborhood hardware store, we can demonstrate a working solar cell in about an hour. Our solar cell is made from cuprous oxide instead of silicon. Cuprous oxide is one of the first materials known to display the photoelectric effect , in which light causes electricity to flow in a material. Thinking about how to explain the photoelectric effect is what led Albert Einstein to the Nobel prize for physics, and to the theory of relativity. Materials you will need The solar cell is made from these materials: A sheet of copper flashing from the hardware store. This normally costs about $5.00 per square foot. We will need about half a square foot.

Electrochemistry INTRODUCTION Part I An electrolytic cell uses electricity to bring about a chemical reaction whereas a voltaic cell uses a chemical reaction to produce electricity. The electrolytic cell used in today's experiment involves the following reaction: M( s 2 H (aq) M aq H g where M represents an unknown metal. As you can see, it is an oxidation -reduction reaction. By measuring the temperature, pressure and volume of hydrogen, and using the Ideal Gas Law equation, PV = nRT, you will be able to determine the number of moles of hydrogen gas formed. From the balanced equation for the reaction and the mass of the metal that has reacted, you can then calculate the number of moles of metal that has reacted and the atomic weight of the metal. Also, it would be interesting to see how the moles of hydrogen produced compares with the moles predicted based on the following relationships: coulombs amperes x seconds one mole of electrons 96,500 coulombs A coulomb represents the amount of electricity carried in one second by a current of one ampere.

57. Electrochemistry In electrochemistry, this can be done by something called a salt bridge which is just an interval of salt solution in contact with the reaction solutions http://www.du.edu/~jcalvert/phys/elechem.htm

Electrochemistry I try to explain clearly the principles of this rather confusing but very useful science. Contents Introduction Oxidation and Reduction Electrolytic Cells Electrode Potentials ... References Introduction In 1797 the English physician George Pearson laboriously charged Leyden Jars at his electric machine, then discharged them through water, carefully collecting the gases that appeared. Finally, he mixed the gases in a dry container and made a spark with his machine. Drops of water collected on the walls of the container when it cooled. He had decomposed water into its constituents, and then recombined them again. The world took little notice. In 1800 Alessandro Volta reported the results of his recent studies to the Royal Society of London, of which he was a member. His momentous achievement was the column, or "pile," of discs of silver, zinc and leather moistened with salt solution, repeated over and over. An alternative was the couronne des tasses , a ring of cups joined by arcs of silver and zinc alternately, filled with dilute salt solution. When the ultimate members of the pile or crown were connected by a conductor, a permanent electric current flowed. Much care was taken to show that it had the same qualities as the electricity from a static machine, principally that it could give a shock, or fuse a fine wire. Electricity was now available in unprecedented amounts with no exertion, but at a much lower pressure. In 1801 Nicholson and Carlisle caused the current to pass through a dilute salt solution and collected the gases that were evolved at the separate platinum electrodes. Twice as much gas was produced at the electrode connected to the zinc of the pile as at the electrode connected to the copper. They may have used different metals, but copper and tin will do as well as silver and zinc. The main idea seemed to be that the metals had to be different. A glowing splint thrust into the copper gas burst into flame, while a glowing splint approaching the zinc gas caused a loud "pop." These gases were, of course, oxygen and hydrogen, only very recently recognized as elements and the constituents of water in Lavoisier's new chemistry.
