Explanation
A solution in which all components comply with Raoult's law. When the solute and solvent are mixed into a solution, there is no thermal effect and volume change, so it is an ideal solution. Another is that when the solute and solvent are similar to each other, and the relative size and interaction force are equal, it is an ideal solution. In chemistry, the ideal solution represents that the heat of solution (change of enthalpy) when the solution is dissolved is zero. For actual solutions, the closer the heat of dissolution is to zero, the more "ideal" the behavior of the solution is; The closer the molecular structure and properties of solute are to the phase of solvent molecule, the closer the behavior of mixed solution is to that of ideal solution. Generally speaking, dilute solution is closer to ideal solution than concentrated solution.
