Correct option: D.
All of these
d
Ideal Solutions generally have characteristics as follows:
Ideal Solutions generally have characteristics as follows:
They follow Raoult's Law. This implies that the partial pressure of components $A$ and $B$ in a solution will be $P_A=P_A^0 \times X_A$.
The enthalpy of mixing of two components should be zero, that is, $\Delta mix\,H =0$. This signifies that no heat is released or absorbed during mixing of two pure components to form an ideal solution
The volume of the mixing is equal to zero that is, $\Delta \operatorname{mix\,V}=0$. This means that the total volume of solution is exactly the same as the sum of the volume of solute and solution. Adding further, it also signifies that there will be contraction or expansion of the volume while the mixing of two components is taking place.
The solute-solute interaction and solvent-solvent interaction are almost similar to the solute-solvent interaction. thus, the correct answer is $D$.
