Hello Gene, My experience in this area is limited to analytical chemistry. We perform a few redox analysis using coulometry. There are two basic categories, potentiostatic coulometry (holding the electric potential constant during the reaction)and amperostatic coulometry (holding the current constant). Of the tests performed, Karl Fischer titration and Bromine number are our primary tests. Coulometry is the name given to a group of techniques in analytical chemistry that determine the amount of matter transformed during an electrolysis reaction by measuring the amount of electricity (in coulombs) consumed or produced. In researching your question, Wikipedia provides some definitions: Electrostatic discharge (ESD) is the sudden and momentary electric current that flows between two objects at different electrical potentials caused by direct contact or induced by an electrostatic field. The term is usually used in the electronics and other industries to describe momentary unwanted currents that may cause damage to electronic equipment. Static electricity refers to the buildup of electric charge on the surface of objects. The static charges remain on an object until they either bleed off to ground or are quickly neutralized by a discharge. Although charge exchange can happen whenever any two surfaces come into contact and separate, a static charge will only remain when at least one of the surfaces has a high resistance to electrical flow (an electrical insulator). Lightning has been documented to cause chemical reactions. Lightning is an electrostatic charge of debated origin. Many researchers are investigating the nitrogen cycle of the atmosphere with relation to electrical storms. Electrostatic charge possibly could be used as a donor of electrons and thus a reducing agent.
