Question
An aqueous solution of hydrochloric acid
Options
A.Obeys Raoult′s law
B.Shows negative deviation from Roult′s law
C.Shows positive deviation from Roult′s law
D.Obeys Henry′s law at all compositions
Solution
Shows negative deviation from Raoult′s law.
If the attraction between different moleculentes, for examples, for example between HCl and H2O molecules, is stronger, solution to the vapour phase will be smaller, then the partial vapour pressure will be smaller than predicted by Raoult’s law and the system exhibits a negative deviation.
