Electrochemical processes are uniformly based on redox (reduction/oxidation) reactions. Think of it as the opposite of a battery. In a battery the chemical process is spontaneous and produces electrical energy, while in an electrolysis you need to put electrical e ....

.... conditions (more safely), with less hazardous waste (better for the environment), and in higher yields (better for your wallet) than a similar process using chemical reagents. Some synthetic processes can only be done using electrochemical methods, and electrochemical methods are used in the large-to-medium-scale synthesis of organic "fine chemicals" because of the financial, safety and environmental advantages. Here's a page outlining some current research by one of my graduate school professors. I can think of at least three common uses of electrochemistry: pH meters and other measuring devices pH meters are electrochemical devices. They meas ....
