A common misconception about vapor pressure lowering is that the solute occupies some of the surface sites in the solution, reducing the percentage of solvent molecules that can potentially overcome the attractive intermolecular forces and transition into the gas phase. (a) Draw a particulate-level sketch of a nonvolatile molecular solute in water and use it to explain why the misconception is incorrect. (b) What is the correct explanation for vapor pressure lowering?

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.
