Explain the solubility rule “like dissolves like” in terms of intermolecular forces that exist in solutions.

उत्तर

A substance dissolves in a solvent if the inter-molecular interactions are similar in both the components. For example, polar solutes dissolve in polar solvents and non-polar solutes in non-polar solvents. Thus, we can say “like dissolves like”.
