Question

Which of the following is false regarding Non-Ideal solutions?

• A. They do not obey Raoult’s law
• B. $\Delta V_{mix}\ne 0$
• C. $\Delta H_{mix}\ne 0$
• D. None of the above

Answer 1

The correct option is D None of the above

Non-Ideal solutions do not obey Raoult’s law.. A non-ideal solution may be defined as the solution in which volume change $(\Delta V_{mix}\ne 0)$ and enthalpy change $(\Delta H_{mix}\ne 0)$ take place on mixing the solute and the solvent in any proportion.
Acetone and $CHC{l}_3$ are the non-ideal solution and shows negative deviation from Raoult's law
