The endpoint in a titration is the point at which the indicator changes color, showing that the titration is complete.
- It is the observable point during the experiment.
- The endpoint should be very close to the equivalence point, where the exact amount of titrant has reacted with the analyte.
- A suitable indicator is used to show this color change.
In short:
The endpoint is the moment you can see in a titration that the reaction is finished.
