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

Options

  1. AAcetic acid versus ammonia
  2. BAcetic acid versus sodium hydroxide
  3. CHydrochloric acid versus ammonia
  4. DHydrochloric acid versus sodium hydroxide.

Correct answer

B. Acetic acid versus sodium hydroxide

Step-by-step solution

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.
