Imagine a sealed container is filled half way with water and the pressure above  the water is measured. When a solid, non-electrolyte solute is added, the pressure is measured to be lower than  before.  1. Why did this solution exhibit a lower vapor pressure than the pure solvent?  2. If the solute was volatile, how might the pressure compare to that of the pure liquid? Explain.

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.
