Volumetric method for acids and bases - chemical methods
Molecular mass of an acid can be ascertained by dissolving a known mass of the acid in water and titrating the solution against a standard solution of an alkali by using phenolphthalein like an indicator. Knowing the volume of alkali solution employed, the mass of the acid that will require 1000 ml of a normal alkali solution for complete neutralisation can be measured. This type of mass of the acid will be its equivalent mass.
