Q47 / 180 · AIIMS 2003 · Chemistry

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

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

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.

Hence, the correct answer is option: 'B'.
