Ideal Solution Vs Non-Ideal Solution

Ideal Solution	Non-Ideal Solution
The interactions between the components are similar to those in the pure components.	The interaction between the components are different from those of the pure components.
There is no enthalpy change on mixing (ΔmixingH = 0).	There is enthalpy change on mixing (ΔmixingH ≠ 0).
There is no volume change on mixing (ΔmixingV = 0).	There is volume change on mixing (ΔmixingV ≠ 0).
Each component obeys Raoult’s law at all temperatures and concentrations, i.e. pA = pA° × xA and pB = pB° × xB where pA and pB are the vapour pressures of the components in the solution.	Their components do not obey Raoult’s law. They show positive and negative deviations from Raoult’s law, i.e. pA ≠ pA° × xA and pB ≠ pB° × xB where pA° is the vapour pressure of the pure component A and pB° is the vapour pressure of pure component B at the same temperature.
