An acidic buffer is prepared by mixing:

An acidic buffer is prepared by mixing:
  1. Strong acid and it's salt with strong base.
  2. Strong acid and it's salt with weak base.
  3. Weak acid and it's salt with strong base.
  4. Equal volumes of equimolar solutions of weak acid and weak base. (The $\mathrm{pK}_{\mathrm{a}}$ of acid $=\mathrm{PK}_{\mathrm{b}}$ of the base)

Solution

Acidic buffer is a mixture of weak acid and its conjugate base or salt of that weak acid with another strong base in a molar ratio ranging from $\frac{1}{10}$ to 10
