Question

A 0.250 L solution that contains 0.010 M HCl and 0.060 M acetic acid was titrated with 0.10 M NaOH. Which best describes what happens?

( ) The NaOH reacts with some of the acetic acid before it begins reacting with HCl.

( ) The NaOH reacts with essentially all of the acetic acid before it begins reacting with HCl.

( ) The NaOH reacts only with the acetic acid.

( ) The NaOH reacts with essentially all of the HCl before it begins reacting with acetic acid

Answer 1

Option (D) seems to be correct i.e. NaOH reacts with essentially all of the HCl before it begins reacting with acetic acid because HCl is stronger acid than acetic acid and hence HCl is more reactive than acetic acid. So, neutralization will start first with HCl.
