Which of the following is not correct for an ideal solution?

ARaoult's law is obeyed for entire concentration range and temperatures
B$$\triangle H_{mix}=0$$
C$$\triangle V_{mix}=0$$
D$$\triangle S_{mix}=0$$
Correct Answer

Solution

For an ideal solution,

Raoult's law is obeyed for entire concentration range and temperatures
The enthalpy change of mixing is zero $$\triangle H_{mix}​=0.$$
The volume of mixing is zero. \triangle $$V_{mix}​=0$$
But the entropy of mixing is not equal to zero. $$\triangle S_{mix}\neq0$$​

Option D is correct.
