Describe electrolysis of fused NACL and aqueous NACL

Electrolysis of Fused NaCl and Aqueous NaCl:

Electrolysis of Fused NaCl: 

• In the electrolysis of fused NaCl, the molten NaCl is placed in an electrolytic cell, and a voltage is applied across the electrodes. 
• The cations, Na+, migrate to the cathode and are reduced to form sodium metal. 
• The anions, Cl-, migrate to the anode and are oxidized to form chlorine gas.

Electrolysis of Aqueous NaCl:

• In the electrolysis of aqueous NaCl, the NaCl is dissolved in water, and a voltage is applied across the electrodes. 
• The cations, Na+, migrate to the cathode and are reduced to form hydrogen gas and the anions, Cl-, migrate to the anode and are oxidized to form oxygen gas. 
• The reaction at the cathode is: 2H+ + 2e- -> H2, and the reaction at the anode is: 2Cl- -> Cl2 + 2e-.
