Question

In the titration of NaOH with vinegar, a student overshot the endpoint (i.e. added too much NaOH solution). How will this affect the calculate percent acetic acid in the vinegar

Answer 1

Overshooting the endpoint leads to a percent acetic acid in vinegar higher than the correct value.

Step-by-step explanation:

When too much NaOH solution is added, the resulting number of equivalent hydronium (OH⁻) will be higher than what it is in reality. This would directly lead to the number of acetic acid moles in the vinegar being found higher than normal.

• In other words, overshooting the endpoint leads to a percent acetic acid in vinegar higher than the correct value.
