Electrolysis of water is a decomposition reaction. The mole ratio of hydrogen and oxygen gases liberated during electrolysis of water is
1:1
2:1
4:1
1:2

Academic Chemistry NCERT Class 10

Correct Answer: (b) 2:1

Explanation: 1 mole of water (H₂O) has 2 moles of Hydrogen and 1 mole of water. Hence mole ratio between hydrogen and oxygen is 2:1.
