Question

Errors occuring during experimental titration cause errors in the final answer. A student uses the pipet bulb to "blow out" the tip of the pipet, adding more vinegar than the expected 20.00 ml. What effect does this have on the calculated concentration of acetic acid in the vinegar? The calculated concentration is higher than the actual real concentration. The calculated concentration is lower than the actual real concentration. The calculated concentration is accurate. The calculated concentration cannot be determined.

Explanation / Answer

Since the titration is finished and the droplet was clinging inside the buret.

So, the calculated concentartion is accurate.
