When HCI is added to the aqueous solution of NaCI, the ionization of NaCI:
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Remains same
- D. First decreases and then increases
Explanation
B) Decreases When HCl is added to the aqueous solution of NaCl, the ionization of NaCl will decrease due to the common ion effect caused by the introduction of additional chloride ions from HCl.

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.
