One way to distinguish between solutions and colloids is to test them with a beam of light. Light passes through solutions but reflects on colloids allowing the beam to become visible. This phenomenon is referred to as “Tyndall effect” or light scattering effect. Based on this information, what can be accurately inferred about the two liquid drug preparations (preps) below? Dispersed phase in prep on the left passes readily through semipermeable membranes while dispersed phase on the right side prep does not. Size of dispersed phase of prep on the right is typically in the range of 1 – 500 nm. Diffusion coefficient, D, for dispersed phase of prep on the left is higher than that for dispersed phase on the right.

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.
