In titration, what term refers to adding titrant beyond the point of complete reaction?

• A. Titration
• B. Buffer
• C. Overtitrations
• D. Endpoint

Answer: (C)

The main idea here is what happens when you keep adding titrant after the reaction has gone to completion. That extra addition is overtitration. In a titration you aim to reach the point where all the analyte has reacted with the titrant (the equivalence point), and you use a signal (the endpoint) to stop near that point. If you go past it, you introduce extra titrant, which skews the calculations and leads to an inaccurate determination of the analyte’s amount. The endpoint is just the observable cue to stop, not the overshoot itself, and the broader process is simply titration. A buffer, by contrast, is a substance that resists pH changes and isn’t about overshooting the reaction.
