Electrochemistry
, Electrochemistry
Electrochemistry is the study of production of
electricity from energy released during
spontaneous chemical reactions and the use
of electrical energy to bring about non-
spontaneous chemical transformations.
, Electrochemical Cells
An electrochemical cell is a device that produces an
electric current from energy released by a
spontaneous redox reaction.
Electrochemical cells have two conductive electrodes,
called the anode and the cathode. The anode is
defined as the electrode where oxidation occurs.
, Types of electrochemical cells
(a)- Galvanic cells or Voltaic Cell
It contain chemicals which undergo spontaneous chemical reactions.
The energy from the chemical reactions is converted to electrical
energy in the form of an electric current.
