Volumetric analysis is a quantitative analytical technique that involves determining the concentration of a substance in a solution by measuring the volume of another solution of known concentration that reacts completely and stoichiometrically with the substance being analyzed. This technique is commonly used in chemistry for determining the concentrations of acids, bases, and metals in a sample. Volumetric analysis is based on the principle of chemical equivalents, where the volumes of two reacting solutions are directly related to the number of moles of reactants present. This method is widely used in various industries, including pharmaceuticals, environmental monitoring, and food testing.
