Electrochemical technologies are an integral part of modern life. In 1800, Nicholson and Carlisle, using Volta's primitive battery as a source, showed that an electric current could decompose water into oxygen and hydrogen. electrons can flow from the oxidized species, the reducing agent or Electrochemistry | Introduction. electrons from a Electrochemistry deals with oxidation/reduction reactions. You can view our. The reaction is a simple oxidation-reduction process, a transfer of two electrons from the zinc to the copper: Zn(s) → Zn2+ + 2e–          Cu2+ + 2e– → Cu(s), The dissolution of the zinc is no longer inhibited by a buildup of negative charge in the metal, because the excess electrons are removed from the zinc by copper ions that come into contact with it. The concentration of hydrated ions Zn+(aq) in the water will typically be around 10–10 M, which for most practical purposes is neglibible. introduces the topic for a course in There will be a flow of electrons from certain areas of a metal surface to other areas through an environment capable of conducting ions. For example, a potential difference of one volt across a typical 10–8 cm interfacial boundary amounts to a potential gradient of 100 million volts per centimeter— a very significant value indeed! The interfacial potential differences which develop in the double layer are generally limited to only a few volts.

Furthermore, experienced readers will find this book useful for solidifying their electrochemical background. Now consider another reaction that is often demonstrated in class or carried out in the lab: when a piece of zinc metal is immersed in an aqueous solution of copper(II) sulfate, the surface of the zinc is rapidly covered with a black coating of metallic copper: The transfer of the electric charge from the copper(II) ion to zinc means that two electrons have been transferred from the zinc atom to the copper. Shorthand notation for galvanic/voltaic cells. Students become familiar with how to run a potentiostat, how to use the Cottrell and Randles-Sevcik . A simple way to accomplish this would be to immerse the zinc in a solution of copper sulfate instead of pure water.
