Question

Which condition is not satisified by an ideal solution?

• A. $\Delta H_{mixing}=0$
• B. $\Delta V_{mixing}=0$
• C. $\Delta S_{mixing}=0$
• D. Obeyance of Raoult's law

Answer 1

Answer: (C)

$\Delta S_{mixing}=0$

Option (C) is correct.
For an ideal solution, $\Delta H_{mixing}=0;\Delta V_{mixing}=0$ and its should obey Raoult's law.
