Which one is not equal to zero for an ideal solution?

A$$\Delta V_{mix}$$
B$$\Delta P=P_{observed}-P_{Raoult}$$
C$$\Delta H_{mix}$$
D$$\Delta S_{mix}$$
Correct Answer

Solution

For an ideal solution,

(A) The volume of mixing is zero. $$\Delta V_{mix}=0$$

(B) The observed pressure is equal to the pressure calculated from Raoult's law, then solution said to be ideal solution.

$$P_{observed}=P_{Raoult}$$

$$\Delta P=P_{observed}-P_{Raoult}=0$$

(C) The enthalpy change of mixing is zero $$\Delta H_{mix}=0$$.

(D) But the entropy of mixing is not equal to zero. $$\Delta S_{mix} \neq 0$$.

Option D is correct.
