WebSep 22, 2024 · Raoult's Law for solid-liquid solution is stated as such in my books that it is applicable for all non-volatile solutes. ... as there are many more or less significant positive and negative deviations from the law. These deviations relate to preference of intermolecular bonding to the same, or to the other molecules. ... WebNon-ideal solutions by definition cannot be dealt with through Raoult's Law. Raoult's Law is strictly for ideal solutions only. A solution shows positive deviation from ideal behaviour when the interaction between them, unlike molecules, is weaker than the like molecules i.e interaction between A-B molecules is weaker than A-A and B-B molecules.
