Solution

The mole ratio of hydrogen to oxygen gases liberated during the electrolysis of water is 2:1.

Here's the step by step explanation:

  1. Electrolysis of water is a decomposition reaction. In this process, an electric current is passed through water to break it down into its constituent elements, hydrogen and oxygen.

  2. The chemical equation for this reaction is: 2H2O(l) → 2H2(g) + O2(g)

  3. From the balanced chemical equation, you can see that two moles of water produce two moles of hydrogen gas and one mole of oxygen gas.

  4. Therefore, the mole ratio of hydrogen to oxygen gases liberated during the electrolysis of water is 2:1.
