A pair of electrodes in contact with an electrolyte solution

An electrochemical cell which spontaneously produces current (or energy) when the electrodes are connected externally by a conducting wire

An electrochemical cell through which current is forced by a battery or some other external source of energy

Oxidation or reduction reaction occurring at an electrode

The electrode at which oxidation occurs

The electrode at which reduction occurs

One in which the half-cell reactions are reversed by reversing the current flow; such a cell is said to be in thermodynamic equilibrium

This consists of a platinum electrode coated with platinum black to catalyze the electrode reaction and over the surface of which hydrogen at 760 mm of mercury is passed

The potential of an electrode measured relative to a standard, usually the SHE

Electrode potential measured in solutions where all reactants and products are at unit activity

The algebraic sum of the individual electrode potentials of an electrochemical cell at zero curren

It is a measure of the driving force of the electrode reaction and is temperature and activity dependent

A potential developed across a boundary between electrolytes differing in concentration or chemical composition

the amount of potential that is lost on the way from the reference electrode to the working electrodes

The additional potential required to cause some electrode reactions to proceed at an appreciable rate

the additional voltage that is needed to carry out electrolysis in addition to the standard cell potential

isolates the reactants but maintains electrical contact between teo halves of the cell

used to sense the presence or change on concentration of the oxidized and reduced form of a redox couple

an electrode that has stable and well known electrode potential

the electrode consist of two concentric glass tube, the inner of which CONTAINS MERCURY in conact with a paste of mercury

this consist of a silver wire, coated with silver chloride and in contact with a solution of potassium cloride saturated with silver chloride

the most widely used electroanalytical technique

used to find concentration of a solution
