Question
What are the characteristics of ideal solutions ?
✓
Answer
The ideal solutions obey Raoult’s law over entire range of concentrations at constant temperature.
In the formation of an ideal solution, heat is neither evolved nor absorbed and enthalpy change for mixing is zero, i.e. $\triangle _{mix} H = 0.$
In the formation of an ideal solution, there is no volume change on mixing two liquid components and the volume of solution is equal to the sum of volumes of two liquid components. $\triangle _{mix} V = 0$
In the ideal solution, solvent$-$solvent, solute$-$solute and solvent$-$solute interactions are comparable.
The vapour pressure of an ideal solution lies between vapour pressures of two pure components.
