FSc Chemistry Book1, CH 10, LEC 4: Ion Electron Method in an Acidic Medium

http://www.dailymotion.com/video/x2pey0g

This video lecture from Electrochemistry  (F.Sc. first year Chemistry) covers the technique to balance a redox equation using Ion electron method in an acidic medium. The method involves an initial separation of two half reactions taken from an ionic equation in which the overall charge is balanced by adding electrons respectively in the reduction and oxidation half reactions. The oxygen atoms are balanced by the addition of water molecules while hydrogen is balanced by the addition of protons since the reaction takes place in an acidic medium containing excess of protons. The two half reactions are then added to get a balanced equation. Find more e-learning material and educational video lectures in Urdu at maktab.pk.
