Vedclass · Answer

(D) The electrolysis of a concentrated aqueous solution of $NaCl$ (brine) involves the following reactions:At the anode: $2Cl^-_{(aq)} \rightarrow Cl_{2(g)} + 2e^-$At the cathode: $2H_2O_{(l)} + 2e^- \rightarrow H_{2(g)} + 2OH^-_{(aq)}$The overall reaction is: $2NaCl_{(aq)} + 2H_2O_{(l)} \rightarrow 2NaOH_{(aq)} + H_{2(g)} + Cl_{2(g)}$Thus,the products formed are $Cl_{2(g)}$,$NaOH_{(aq)}$,and $H_{2(g)}$.Hence,the correct option is $D$.

What products are formed during the electrolysis of a concentrated aqueous solution of $NaCl$?
$I. Cl_{2(g)}$
$II. NaOH_{(aq)}$
$III. H_{2(g)}$
