Ionization of KCIO3 is suppressed by:
Correct answer: C. Adding KCI.
- A. Increasing temperature.
- B. Adding NaNO3
- C. Adding KCI.
- D. Decreasing temperature.
Explanation
KCIO3⇌,K++CIO3-KCI⇌ K++CI-The solubility of less soluble salt KCIO3 in water is suppressed by addition of more soluble salt KCI by 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.
