Question

The next six questions explore the effect of errors occurring during experimental titrations on the final answer. Sometimes the error skews the calculation and returns an answer that is too high or too low. Sometimes an error has no effect and sometimes it makes completing the calculation impossible. Decide what would happen in each case. A student forgets to fill the buret tip with NaOH before beginning the titratioa What effect does this have on I 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

If burette tip is not filled with NaOH solution then titration requires more volume of base than the normal usage.If more volume of base requires, it indicates that the concentration of Acid is more.

The calculated concentration is higher than the real concentration.
