Which of the following is satisfied by an ideal solution?

AFormation of an azeotropic mixture
B$$\triangle S_{mix} = 0$$
CRaoult's law is obeyed under particular set of conditions only
D$$ \triangle H_{mix} = 0$$
Correct Answer

Solution

An ideal solution obeys Raoult's law in any condition. For an ideal solution, the enthalpy of the mixture remains constant and there is no volume change. Hence, $$\Delta H_{mix} = 0$$ and $$\Delta V_{mix} = 0$$.

Hence the correct option is D.
