उत्तर
The volume ratio of hydrogen and oxygen gases liberated during electrolysis of water is 2 : 1.
Explanation:
Electrolysis of water decomposes it into hydrogen and oxygen gases. The ratio of gases produced is based on the chemical equation.
\[\ce{2H2O_{(l)} -> 2H2_{(g)} + O2_{(g)}}\]
2 molecules of hydrogen gas are produced for every 1 molecule of oxygen gas. Hence, the volume ratio of hydrogen to oxygen is 2 : 1.
