Answer: (3) When its components have both the above characteristics
An ideal solution is a mixture in which the molecules of different species are distinguishable, however, unlike the ideal gas, the molecules in ideal solution exert forces on one another. When those forces are the same for all molecules independent of species then a solution is said to be ideal.
Ideal Solution Characteristics
By combining a solute and a solvent with similar molecular structure and size, an ideal solution can be produced. When two substances, X and Y, are mixed together, we can see that there are many intermolecular forces in play.
