Buffer action can be explained by:
Correct answer: D. A and B
- A. Le-Chatelier's principle
- B. Common ion effect
- C. Solubility Product
- D. A and B
Explanation
Buffer action can be explained by Le-Chatelier's principle as the constituents dissociate into their ions at equilibrium, and can also be explained by common ion effect as well because both the salt and the acid/base contains a same ion leading to common ion effect .

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.
