8.23 Chlorine is used to purify drinking water. Excess of chlorine is harmful. The excess of chlorine is removed by treating with sulphur dioxide. Present a balanced equation for this redox change taking place in water
Base equation- --------------(have to remember)
Now we have to balance the oxidation half and reduction half.
oxidation half =
balancing- Oxygen is balanced by adding water molecule, Hydrogen is balanced by ion and for charge add (electron)
Balancing- to balance charge add an electron
Now add both balanced oxidation half and reduction half, we get
