Answer:
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.
