21. 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.

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)

A stabilized suspension of nanotubes is introduced in a capillary containing an aqueous metal salt solution, and a high electric field is applied to orientate and polarize the individual tubes. During their transport through the capillary under sufficient polarization (30 kV), each nanotube is the site of water oxidation on one end and the site of metal ion reduction on the other end with the size of the formed metal cluster being proportional to the potential drop along the nanotube.

Department of Chemistry Stage 2 Chemistry Social Relevance Projects. Home Contents Cross Referenced Index Experimental Procedures ... Data Analysis Electrochemistry Introduction Electrochemistry can be broadly defined as the study of charge-transfer phenomena. As such, the field of electrochemistry includes a wide range of different chemical and physical phenomena. These areas include (but are not limited to): battery chemistry, photosynthesis, ion-selective electrodes, coulometry, and many biochemical processes. Although wide ranging, electrochemistry has found many practical applications in analytical measurements. Electroanalytical chemistry A good working definition of the field of electroanalytical chemistry would be that it is the field of electrochemistry that utilizes the relationship between chemical phenomena which involve charge transfer (e.g. redox reactions, ion separation, etc.) and the electrical properties that accompany these phenomena for some analytical determination. This relationship is further broken down into fields based on the type of measurement that is made. Potentiometry involves the measurement of potential for quantitative analysis, and
