Question

Write two differences between an ideal solution and a non-ideal solution.

Answer 1

Ideal Solution	Non-ideal Solution
An ideal solution of the components A and B is defined as the solution in which the intermolecular interactions between the components (A–B attractions) are of the same magnitude as the intermolecular interactions found in the pure components (A–A attractions and B–B attractions).	A non-ideal solution of the components A and B is defined as the solution in which the intermolecular interactions between the components (A–B attractions) are of different magnitude as the intermolecular interactions found in the pure components (A–A attractions and B–B attractions).
ΔmixH = 0 and ΔmixV = 0.	ΔmixH ≠ 0 and ΔmixV ≠ 0.
Solutions which obey Raoult’s law over the entire range of concentrations are know as ideal solutions	Solutions which do not obey Raoult’s law over the entire range of concentration are know as non-ideal solutions
