Concentration determination by means of density

The density of the mixture is a function of its composition. Thus, the density value of a binary mixture can be used to calculate its composition with the aid of concentration tables. Typical two-component mixtures are e.g. alcohol-water solutions, sugar-water solutions, salt-water solutions, and acids or bases dissolved in water.
