Any chemically and physically homogeneous mixture of two or more substances is said to be a solution. It is possible to have solutions of solids in liquids, liquids in liquids, gases in liquids, solids in solids, etc. Depending upon the size of the dispersed particles we recognise true solutions, colloidal solutions and suspensions. If sugar is dissolved in water, it is supposed that the ultimate particle is of molecular dimensions and that a true solution is formed. On the other hand, if very fine sand is mixed with water, a suspension of comparatively large particles, each consisting of many molecules is obtained. Between these two extremes lie colloidal solutions, from the pharmaceutical stand-point solutions of solids in liquids are of greatest importance and many quantitative data are available on the properties of such solutions.
