Question

Which of the following is not an example of an Ideal solution?

Answer 1

An ideal solution may be defined as the solution in which no volume change $(\Delta V_{mix}=0)$ and no enthalpy change $(\Delta H_{mix}=0)$ take place on mixing the solute and the solvent in any proportion.
For ideal solution, solvent-solute interaction is equal to solvent-solvent and solute-solute interactions.
Ethyl alcohol + Water is a non-Ideal solution.
