QJEEM23Ch404a: JEE Main 2023 Chemistry - Class 12 JEEM23Ch404a Solution: Which one of the following statements is correct for…

Which one of the following statements is correct for electrolysis of brine solution?

Multiple Choice Options

  • A O2 is formed at cathode
  • B H2 is formed at anode
  • C Cl2 is formed at cathode
  • D OH− is formed at cathode

Step-by-Step Verified Solution

Cathode : H2O(l)+e−⟶12H2(g)+OH(aq)−\mathrm{H}_2 \mathrm{O}_{(l)}+e^{-} \longrightarrow \frac{1}{2} \mathrm{H}_{2(g)}+\mathrm{OH}_{(a q)}^{-}

Anode :Cl(aq)−⟶12Cl2(g)+e−: \mathrm{Cl}_{(a q)}^{-} \longrightarrow \frac{1}{2} \mathrm{Cl}_{2(g)}+e^{-}
