For acidic buffer, pH < pKa if:
Correct answer: C. [salt] < [acid].
- A. [salt] = [acid].
- B. [salt] >[acid].
- C. [salt] < [acid].
- D. [salt] >[base].
Explanation
For acidic buffer pH will be less than pKa, if [salt]<[acid]pH will be greater than pKa if [salt]> [acid]pH will be equal to pKa if [salt] = [acid].

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
