Titration of Strong Base with a Weak Acid

APCHEM-JCESXP

There are two 25.0 mL unmarked samples. One sample is $HCl$ and the other sample is $HF$. Given 0.200 M $KOH$, you titrate each sample separately to determine the equivalence point.

Which of the following would assist in identifying the samples?

A

The equivalence point for $HCl$ would be found at a pH < 7, while the equivalence point for $HF$ would be found at a pH = 7.

B

The equivalence point for $HCl$ would be found at a pH > 7, while the equivalence point for $HF$ would be found at a pH < 7.

C

The equivalence point for $HCl$ would be found at pH = 7, while the equivalence point for $HF$ would be found at a pH < 7.

D

The equivalence point for $HCl$ would be found at a pH = 7, while the equivalence point for $HF$ would be found at a pH > 7.
