Balancing Ion-Electron Equations | Higher Chemistry

Learn in the following video how to balance out an ion electron equation step by step. An ion-electron equation can be balanced by adding appropriate numbers of:

1. Water molecules - to balance out Oxygen atoms  
2.Hydrogen ions - to balance out Hydrogen atoms
3. Electrons - to balance out the overall charge (ADD to side which is Higher)

Three worked examples and then the following PPQ are worked through:
H2016 - MC8
H2012 - MC9
