An acidic buffer is prepared by mixing:

Options

  1. AStrong acid and it's salt with strong base.
  2. BStrong acid and it's salt with weak base.
  3. CWeak acid and it's salt with strong base.
  4. DEqual volumes of equimolar solutions of weak acid and weak base. (The pK _ a of acid = PK _ b of the base)

Correct answer

C. Weak acid and it's salt with strong base.

Step-by-step 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 1 10 to 10
