Which of the following is a common error in titration that leads to an overestimation of the analyte concentration?
Correct answer: A. Rinsing the burette with distilled water instead of the titrant
- A. Rinsing the burette with distilled water instead of the titrant
- B. Reading the burette at the top of the meniscus
- C. Adding too much indicator
- D. Using a dry conical flask
Explanation
Rinsing with water dilutes the titrant, requiring more volume to reach the endpoint, thus overestimating the analyte concentration.
