Electrochemistry
In an electrolytic cell external source of voltage is used to bring about
a chemical reaction The electrochemical processes are of great importance
in the laboratory and the chemical industry One of the simplest electrolytic
cell consists of two copper strips dipping in an aqueous solution of
copper sulphate If a DC voltage is applied to the two electrodes, then
Cu 2+ ions discharge at the cathode (negatively charged) and the following
reaction takes place:
Cu2+(aq) + 2e– ® Cu (s)
(2
