Electrochemistry encompasses chemical and physical processes that involve the transfer of charge. Some examples are electroplating, iron oxidation (rusting), solar-energy conversion, energy storage (batteries), photosynthesis, and respiration. Links to background documents on redox chemistry are listed below. Electroanalytical chemistryThere are two categories of electrochemical processes that are applied to quantitative measurements: potentiometry - measurement of a potential (voltage)electrolytic methods - measurement involving a current In both of these categories, an electrochemical measurement can be related to the concentration of an analyte. See the Electrochemistry Index for links to specific electrochemical techniques.
