What is titrating?

Titrating is a laboratory method of measuring the concentration of an unknown solution using a known solution. It involves slowly adding the known solution, called the titrant, to the unknown solution, called the analyte until the reaction is complete. The point at which the reaction is complete is called the endpoint and is determined by using an indicator or by measuring a physical property such as color change or pH level.

The purpose of titrating is to determine the concentration of the analyte, which can assist in the identification of unknown substances, as well as the quantification of a substance in a mixture. Titrating can also be used to determine the acidity or basicity of a solution, and to determine the concentration of acids, bases, or salts.

To perform a titration, precise measurements of both the analyte and titrant are required, along with careful observation and record-keeping. Titrations can be performed using a variety of methods, including volumetric titration, gravimetric titration, and coulometric titration. The accuracy of titration can depend on factors such as temperature, concentration, and the choice of indicator.
