Question

Ideal solutions obey ______ law and they ______ form azeotropic mixtures.

Answer 1

Ideal solutions obey Raoult’s law and they do not form azeotropic mixtures.

Explanation:

Ideal solutions strictly follow Raoult’s law at all compositions and temperatures, meaning the partial vapour pressure of each component is directly proportional to its mole fraction. These solutions exhibit no enthalpy or volume change on mixing, and because their vapour and liquid compositions differ, they do not form azeotropes.
