What is the purpose of titration?

The purpose of titration is to determine the amount of substance present in a solution by reacting it with a known amount of another substance. This involves adding a solution of known concentration, called the titrant, to the solution of unknown concentration, called the analyte, until the reaction reaches completion. The point at which the reaction is complete is known as the endpoint, which is usually indicated by a color change or other physical change. From the volume of the titrant used, the concentration of the analyte can be calculated. Titration is commonly used in chemical analysis to determine the concentration of acids, bases, metals, and other substances in a solution.
