Solutions differ from suspensions and emulsions in their homogeneity or uniformity, since suspensions and emulsions are heterogeneous, these mixtures are cloudy or layered.
For example, an emulsion is formed by shaking gasoline and water (inhomogeneous, layered mixture), a suspension – when shaking clay with water (inhomogeneous, cloudy mixture), a solution – dissolved salt in water (homogeneous mixture).
