Electrochemistry basics ppt
WebElectrochemistry Introduction Electrochemistry deals with interconversion of electrical and chemical energy. Many chemical changes can be clearly related to the electrons that move from one species to another. Often, this electron exchange can be captured to do electrical work external to the chemical system (storage battery, fuel cell).

WebElectrochemical Cells Two half reactions are separated in two different beakers with a wire connecting them. Wire allows the current (e-) to travel between beakers. Flow of e- through the wire can be used to do work. Electrochemical cells can be used to produce electricity from a redox reaction or can use electricity to produce a redox reaction. 7 WebElectron transfer reactions are oxidation-reduction or redox reactions. Results in the generation of an electric current (electricity) or be caused by imposing an electric current. …
