Question

What are the conditions for an ideal solution?

• A. $\Delta V_{mix}=0$
• B. $\Delta V_{mix}\ne 0$
• C. $\Delta H_{mix}=0$
• D. $\Delta U_{mix}=0$

Answer 1

Answer: (A), (C)

The correct options are
A $\Delta V_{mix}=0$
C $\Delta H_{mix}=0$

For ideal solutions, during preparation there should not be any change in volume & no energy should be absorbed or emitted.
So,
$\Delta V_{mix}=0$ (change in volume =0)
$\Delta H_{mix}=0$ (change in Enthalpy =0)
