問題一覧

A pair of electrodes in contact with an electrolyte solution

electrochemical cell

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

galvanic

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

electrolysis

Oxidation or reduction reaction occurring at an electrode

half cell reaction

The electrode at which oxidation occurs

anode

The electrode at which reduction occurs

cathode

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

reversible cell

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

standard hydrogen electrode

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

electrode potential E

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

standard electrode potential

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

theoretical cell potential

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

electrode potential E

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

liquid junction potential

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

ohmic drop IR

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

activation overpotential

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

concentration overpotential

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

salt bridge

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

indicator electrode

an electrode that has stable and well known electrode potential

reference electrode

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

calomel electrode

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

silver silver electrode

the most widely used electroanalytical technique

potentiometry

used to find concentration of a solution

potentiometry
