Write down the limitation of Henry,s law.

Explanation

(i) Henry's law is applicable at moderate temperature and pressure only.
(ii) Only the less soluble gases obeys Henry's law
(iii) The gases reacting with the solvent do not obey Henry's law For example ammonia or HCl react with water and hence does not obey this law.
` NH_3+H_2O rArr NH_4^(+) +OH^(-) `
(iv) The gases obeying Henry's law should not associate or dissociate while dissolving in the solvent.
