Which one of the following pairs of solution is not an acidic buffer ?
HClO4 and NaCIO4
CH3COOH and CH3COONa
H2CO3 and Na2CO3
H3PO4 and Na3PO4
Buffer Solutions -
The solutions which resist change in pH on dilution or with addition of small amounts of acid or alkali are called buffer solution.
- wherein
Many body fluids e.g. blood
HClO4 Completing dissociates in an aqueous solution become it is a strong acid. It is salution with it's salt form a buffer as it cant resist changes in pH.
