ELECTROCHEMISTRY
,ELECTROCHEMISTRY
INTRODUCTION:
Electrochemistry is the branch of chemistry which deals with inter conversion of electrical energy and chemical energy
takes place through oxidation-reduction (Redox) reactions.
Redox –both oxidation & reduction reactions
Oxidation-Loss of electrons
Reduction-Gain of electrons
, Electromotive force (E.M.F.) OF CELL
The potential difference between two electrodes of a galvanic cell which causes the flow of current from one electrode
(higher potential) to the other (lower potential) is called the E.M.F.
Ecell=Ecathode - E anode
Eocell=Eocathode - Eoanode
