JEE MAIN - Chemistry (2023 - 31st January Morning Shift - No. 12)
Which one of the following statements is correct for electrolysis of brine solution?
$$\mathrm{O}_{2}$$ is formed at cathode
$$\mathrm{H}_{2}$$ is formed at anode
$$\mathrm{Cl}_{2}$$ is formed at cathode
$$\mathrm{OH}^{-}$$ is formed at cathode
Explanation
Cathode : $\mathrm{H}_2 \mathrm{O}_{(l)}+e^{-} \longrightarrow \frac{1}{2} \mathrm{H}_{2(g)}+\mathrm{OH}_{(a q)}^{-}$
Anode $: \mathrm{Cl}_{(a q)}^{-} \longrightarrow \frac{1}{2} \mathrm{Cl}_{2(g)}+e^{-}$
Anode $: \mathrm{Cl}_{(a q)}^{-} \longrightarrow \frac{1}{2} \mathrm{Cl}_{2(g)}+e^{-}$
