MCQ

If liquids $A$ and $B$ form an ideal solution

A
The free energy of mixing is zero
B
The free energy as well as entropy of mixing are zero
✓
Enthalpy of mixing is zero
D
The entropy of mixing is zero

✓

Answer

Correct option: C.

Enthalpy of mixing is zero

c
For an ideal solution, we know that:-

$a) \,V_{\text {mix }}=0$

$b) \,H _{\text {mix }}=0$

$c) \,\Delta G _{\operatorname{mix}}=- ve$
