Ideal solutions obey __________ law and they _________ form azeotropic mixtures.

ARaoult's; do not
Correct Answer
BHenry's; do not
CRaoult's; do
DIon effect; do not

Solution

According to Raoult's law, the partial vapour pressure of any volatile component of a solution is the product of vapour pressure of that pure component and the mole fraction of the component in the solution.

Azeotropes are constant boiling mixtures. Their compositions do not change during distillation. Ideal solutions obey Raoult's law and they do not form azeotropic mixtures.
