Which of the following reactions takes place at anode during the electrolysis of molten NaCl?

Step-by-step solution

During the electrolysis of molten NaCl , the ions present are Na ^+ and Cl ^- . At the anode, oxidation takes place. The chloride ions ( Cl ^- ) migrate to the anode and lose electrons to form chlorine gas. The reaction at the anode is: 2 Cl ^-_ (l) Cl _ 2(g) + 2 e ^- At the cathode, reduction takes place. The sodium ions ( Na ^+ ) migrate to the cathode and gain electrons to form liquid sodium. The reaction at the cathode is: Na ^+_ (l) + e ^- Na _ (l) Answer: 2 Cl ^-_ (l) Cl _ 2(g) + 2 e ^-
