NH_(3) and HCI do not obey Henry's law. Why ?

Answer»

Solution :(i)Henry's law is applicable at moderate TEMPERATUREPRESSURE only.
Only the less soluble gases obeys Henry's law
(III)The gases reacting with solvent do not obey Henry's law. For example, ammonia a HCI REACTS with water and hence does not obey this law.
`NH_(3)+H_(2)O hArr NH_(4)^(+)+OH^(-)`
(iv)The gases obeying Henry's law should not associate or dissociate while dissolving in the solvent .
