APFIVE Acid-Base Titration Analysis
In an acid-base titration, a student uses sodium hydroxide to neutralize hydrochloric acid. They expect to use 50 mL of NaOH solution but end up using 75 mL to reach the endpoint. They conclude that their NaOH solution is less concentrated than assumed. What mistake did the student make?
A
They incorrectly calculated the molarity of the NaOH solution.
B
They forgot to account for the volume of HCl in the solution.
C
They did not make a mistake; their conclusion about the NaOH concentration is correct.
D
They used an incorrect indicator for the titration endpoint.
