Step 1: Understand that electrolysis is a process that uses electricity to break down a substance.
Step 2: Know that NaCl solution is a mixture of sodium chloride (table salt) and water.
Step 3: Identify the two electrodes used in electrolysis: the anode (positive electrode) and the cathode (negative electrode).
Step 4: Remember that during electrolysis, different substances are produced at the anode and cathode.
Step 5: At the anode, chloride ions (Cl-) from the NaCl solution lose electrons and are oxidized.
Step 6: The oxidation of chloride ions produces chlorine gas (Cl2) at the anode.

Electrolysis – The process of using electrical energy to drive a non-spontaneous chemical reaction, specifically the breakdown of ionic compounds in solution.
Anode Reaction – The site of oxidation in electrolysis where electrons are released, leading to the production of gases or other products.
NaCl Electrolysis – The electrolysis of sodium chloride solution, which typically produces chlorine gas at the anode and hydrogen gas at the cathode.
