Question

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

• A. $\Delta {{S}_{mixing}}=0$
• B. $\Delta {{H}_{mixing}}=0$
• C. $\Delta {{V}_{mixing}}=0$
• D. It obeys Raoults law

Answer 1

Answer: (A)

$\Delta {{S}_{mixing}}=0$

Answer 2

In the formation of an ideal solution, the randomness of particles always increase, hence, $\Delta \,{{S}_{mixing}}>0.$
