Vedclass · Answer

(D) During the electrolysis of an aqueous solution of $NaF$ using inert electrodes,water molecules are preferentially oxidized at the anode rather than fluoride ions because the oxidation potential of water is lower than that of fluoride ions.At the cathode: $2H_{2}O + 2e^{-} \longrightarrow H_{2} + 2OH^{-}$.At the anode: $2H_{2}O \longrightarrow O_{2} + 4H^{+} + 4e^{-}$.Even if $F_{2}$ were produced,it would react with water to form $O_{2}$ as follows: $2F_{2} + 2H_{2}O \longrightarrow 4HF + O_{2}$.Therefore,the final product obtained at the anode is $O_{2}$.

If an aqueous solution of $NaF$ is electrolysed between inert electrodes,the product obtained at anode is
