Given below is a reaction showing Chlor-alkali process :\(2NaCl \,(aq) + 2H_2O \,(l)\) \(\longrightarrow\) \(\underset{(A)}{2NaOH\,(aq)} + \underset{(B)}{Cl_2\,(g)} + \underset{(C)}{H_2\,(g)}\)The products A, B and C are produced respectively :(a) At the anode, at the cathode, near the cathode(b) Near the cathode, at the anode, at the cathode(c) At the cathode, near the cathode, at the anode(d) At the anode, near the cathode, at the cathode |

Answer» Correct answer is (b) Near the cathode, at the anode, at the cathode \(2NaCl \,(aq) + 2H_2O \,(l)\) \(\overset{\text{elecrolysis}}{\longrightarrow}\) \(\underset{(A)\\ \text{(near cathode)}}{2NaOH\,(aq)} + \underset{(B)\\ \text{(Anode)}}{Cl_2\,(g)} + \underset{(C)\\ \text{(cathode)}}{H_2\,(g)}\) When electricity is passed through an aquious solution of sodium chloride (brine), chlorine gas is given off at the anode and Hydrogen gas at the cathode. Sodium Hydroxide solution is formed near the cathode. |
