Electrolysis:

“Decomposition of a compound by passing electricity through is called Electrolysis”.

Electrolysis is the break down of a compound by electricity.

Electrolyte:

A compound that does not conduct electricity in solid form but it only conducts in molten or solution form is called Electrolyte.

 

Electrolytic cell:

It is a device that uses electrical energy to start a chemical reaction.

Electrodes:

These are rods (plates) made up of graphite or metals through which current enters or leave.

 

Anode:
The positive electrode is called Anode.

Cathode:

The negative electrode is called Cathode.

Redox reaction:

A reaction that involves both oxidation and reduction-reaction is called redox reaction.

 Oxidation:

Loss of electron by an atom is called oxidation.

Reduction:

Gain of electron by an atom is called reduction.

Ionic half equation:

“The equations used to represent oxidation-reaction at anode and reduction-reaction at cathode are called ionic half equations”.
