correct option please?
Brine is electrolysed by using inert electrodes.The reaction at anode is.......................

 

Dear Student,


Electrolysis of brine in presence of inert electroldes occur asAt anode: 2Cl-(aq)  Cl2(g)+2e-Atcathode : 2H2O(l)+2e- 2OH-(aq) +H2(g)Overall reaction : 2NaCl +2H2O  Cl2 +H2 +2NaOHHence, correct answer is (1)This is due to higher oxidation potential of Cl-.
