Which of the following products is NOT formed when electricity is passed through an aqueous solution of sodium chloride?

Oxygen gas is not formed when electricity is passed through an aqueous solution of sodium chloride. This electrolytic process is named after its primary products: chlorine and an alkali. During electrolysis, chlorine gas is released at the anode, while hydrogen gas is released at the cathode. Sodium hydroxide solution is formed near the cathode, as the sodium ions react with the hydroxide ions remaining in the water.
