Question

Define electrode and electrode potential.​

Answer 1

Explanation:

electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). The word was coined by William Whewell at the request of the scientist Michael Faraday from two Greek words: elektron, meaning amber (from which the word electricity is derived), and hodos, a way.

The electrophore, invented by Johan Wilcke, was an early version of an electrode used to study static electricity.

electrode potential

Electrode potential, E, in chemistry or electrochemistry, according to an IUPAC definition,[1] is the electromotive force of a cell built of two electrodes:

on the left-hand side of the cell diagram is the standard hydrogen electrode (SHE), and

on the right-hand side is the electrode in question.

The SHE is defined to have a potential of 0 V, so the signed cell potential from the above setup is

Ecell = Eleft (SHE) − Eright = 0 V − Eelectrode = Eelectrode.

SHE is cathode and electrode is anode

Answer 2

Explanation:

Electrode :- Solid electric conductor through which an electric current enters or leaves on electrolytic cell or the medium is called electrode .

Electrode potential:- The electric potential difference set up the metal and it's ion in the solution is called electrode potential .
