Vedclass · Answer

(B) Anode: The electrode of an electrochemical cell at which oxidation occurs.Cathode: The electrode of an electrochemical cell at which reduction occurs.Electrolysis of molten $NaCl$ or fused $NaCl$:Sodium ions $(Na^+)$ migrate to the cathode,where they gain electrons and are reduced to sodium metal:$Na^+ + e^- \longrightarrow Na_{(s)}$Chlorine ions $(Cl^-)$ migrate to the anode. They give up their electrons to the anode and are oxidized to chlorine gas:$Cl^- \longrightarrow \frac{1}{2} Cl_{2(g)} + e^-$Overall reaction:$2 NaCl_{(l)} \longrightarrow 2 Na_{(s)} + Cl_{2(g)}$Therefore,the product obtained at the anode is $Cl_{2(g)}$.
