Question

For an ideal solution, which of the following is/are true?
Here
$\Delta H_{mix}$ is the enthalpy of mixing.
$\Delta V_{mix}$ is the volume of mixing.

• A. Solvent-solute interaction is equal to solvent-solvent and solute-solute interactions
• B. $\Delta V_{mix}=0$
• C. $\Delta H_{mix}=0$
• D. All of the above.

Answer 1

The correct option is D All of the above.

Ideal solutions:
Solvent-solute interaction is equal to solvent-solvent and solute-solute interactions. There should be no association or dissociation of solute.
$\Delta S_{mix}>0$
$\Delta V_{mix}=0$
$\Delta H_{mix}=0$
Ideal solutions follow Raoult's Law.
