Final answer:
The electrolysis of both molten sodium chloride and aqueous sodium chloride produces chlorine gas.
Step-by-step explanation:
The statement is true.
The electrolysis of both molten sodium chloride and aqueous sodium chloride produces chlorine gas. In the case of molten sodium chloride, the electrolysis process involves the migration of sodium ions to the cathode, where they pick up electrons and are reduced to form sodium metal.
At the anode, chloride ions lose electrons and undergo oxidation to form chlorine gas. In the case of aqueous sodium chloride, water molecules are reduced at the cathode instead of sodium ions, producing hydrogen gas and hydroxide ions.
However, chlorine gas is still produced at the anode, just like in the molten sodium chloride electrolysis.
