Question

In which of the following acid-base titration, $pH$ is greater than $8$ at equivalence point?

• A. Acetic acid versus ammonia
• B. Acetic acid versus sodium hydroxide
• C. Hydrochloric acid versus ammonia
• D. Hydrochloric acid versus sodium hydroxide

Answer 1

Answer: (B)

Acetic acid is a weak acid while sodium hydroxide is a strong base. Therefore at the equivalent point, there will be enough hydroxide ions left.
