NEETChemistryIonic EquilibrumMCQ+4 / −1
Which one of the following pairs of solution is not an acidic buffer ?
  1. A
    CH3COOH and CH3COONa
  2. B
    H2CO3 and Na2CO3
  3. C
    H3PO4 and Na3PO4
  4. D
    HClO4 and NaClO4
View written solutionFree

Correct answer: D

An acidic buffer is a mixture of a weak acid and its salt with a strong base. Among CH3COOH, H2CO3, H3PO4 and HClO4, the HClO4 is a strong acid while all other are weak acid thus, HClO4 and NaClO4 does not constitute to form an acidic buffer.
