A solute is dissolved in a solvent only if the solute-solvent interactions are stronger than the solute-solute and solvent-solvent interactions. A solute will not dissolve if the solute-solvent forces of attraction are weaker than individual solute and solvent intermolecular attractions. Why is naphthalene, an organic substance, soluble in Kerosene, while NaCl (inorganic) is not? Why is NaCl soluble in H2O while naphthalene is not? Explain the answer in terms of the forces between the molecules that are present in the mentioned compounds.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
