Interpretation Introduction

Interpretation:

The diagrams that represent the given system after electrolysis should be identified from the given diagrams.

Concept introduction:

Electrolysis of aqueous sodium chloride will result in the formation of chlorine gas and hydrogen gas.

The half-cell reaction was given below.

${\text{anode (oxidation) 2Cl}}^{\text{-}}{}_{\text{(aq)}}\stackrel{}{\to }{\text{Cl}}_{\text{2}}{}_{\text{(g)}}{\text{+2e}}^{\text{-}}$

$cathode(reduction):2H_{2}O+2e^{-}\to H_2+2O{H}^{-}$
