In electrochemistry, we study reactions which produce electricity and other

chemical reactions which take place with the help of electricity. The first type

of reactions occur spontaneously but second type of reactions are forced to

occur and work is done on the system.

Electrolytes conduct electricity in their aqueous solution or in molten state. The

electrolytic conductance depends upon concentration of electrolyte, nature of

electrolyte, etc.

Electro-chemistry: The branch of chemistry which deals with relationship

between chemical energy and electrical energy and how one can be converted

into another is known as electrochemistry.
