Which two gases are produced during the electrolysis of water?
Answer and explanation
Correct answer: Hydrogen and oxygen
Electrolysis of water is a decomposition reaction in which electric current breaks water into its constituent elements: \(2H_2O \rightarrow 2H_2 + O_2\). Thus, hydrogen and oxygen gases are produced, so option A is correct. Option D includes hydrogen, but nitrogen is not a constituent of water.
