Singapore GCE O level Chemistry: The commonly made mistake series 1- Electrolysis.

In this video " The commonly made mistake GCE O level Chemistry series 1", I will share with you the technique of getting the charge of the metal ion in a simple way during electrolysis process.
First concept: the number of mole of electrons are the same within the same electrolytic cell.
Second concept: The metals are formed through reduction process over the cathode.
Make sure your ionic equations are balanced. : )
