According to the chemical education digital library, titration is important because it helps determine the unknown concentration of a reactant it is a laboratory method generally used in analytical chemistry, and it involves gradually adding one solution to another until the chemical amount of the. The purpose of titration is to determine an unknown concentration in a sample using an analytical method titration requires three basic components: a liquid of known molarity or normality, called the titrant, the sample or liquid in need of measuring, called the titrand, and a calibrated device for dispensing the titrant drop by drop into the titrand. Titration part 1: scientific introduction the technique known as titration is an analytical method commonly used in chemistry laboratories for determining the quantity or concentration of a substance in a solution.
