The molar solubility of sparingly soluble salt AB3 is "S" mol/dm3, the corresponding solubility product Ksp is given in term of Ksp by the reaction:
Correct answer: C. S=(Ksp/ 27)1/4
- A. S=(Ksp/ 128 )1/4
- B. S=(27Ksp)1/3
- C. S=(Ksp/ 27)1/4
- D. S=(Ksp/ 81)1/4
Explanation
AB3 ⇌ A+3+3 B-1s s 3sFor a compound having four ionsKsp=[A+3][B-1]3Ksp (s).(3s)3Ksp=27s4s = (Ksp/27)1/4

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.
