This video lecture from Electrochemistry (F.Sc. first year Chemistry) covers the theory of electrode potential. When a spontaneous redox reaction occurs in the two half cells of the galvanic cell, a charge is set up on each of the two electrodes creating a potential difference between the two electrodes. The lecture also covers a qualitative description of the potential difference on a charged plate. Find more e-learning material and educational video lectures in Urdu at maktab.pk.
