Which Among The Following Gas Will Greatly Deviate From Henrys Chemistry Question

Which among the following gas will greatly deviate from Henry’s law in water

Options

(a) H₂
(b) N₂

(d) CO₂

Correct Answer:

CO₂

Explanation:

Gases obey Henry’s law provided
(i) the gas is not highly soluble and does not enter into chemical combination with the solvent.
(ii) the gas does not dissociate.
CO₂ does not obey Henry’s law in water as it combines with H₂O to form carbonic acid. CO₂ is more soluble than hydrogen and oxygen in water.
