Answer #1

Ans :

To balance the redox reaction using the half reaction medium in acidic medium , start by writing the oxidation and reduction half reaction seperately.

Then balance all the elements except hydorgen and oxygen.

Then balance oxygen and hydrogen by adding water molecules and protons respectively. Balance the charges by adding electrons and add the two half reactions together.

Simplify the reaction to get the balanced redox reaction as :

2NO3- + 6Cl- + 8H+ = 2NO + 3Cl2 + 4H2O
