During titration, what is the goal of reaching the endpoint?

In titration, reaching the endpoint is a critical goal because it signifies that the reaction between the titrant and the analyte is complete. This point is often indicated by a color change or another measurable signal, allowing the experimenter to determine the precise volume of titrant required to react completely with the substance being analyzed. By knowing the volume and concentration of the titrant used, one can calculate the concentration of the analyte, which is the ultimate objective of the titration process.

Achieving this endpoint is essential for obtaining accurate results in quantitative analysis, ensuring that the concentration of unknown solutions can be determined reliably.
