Question

1 How do we represent the equilibrium constant for complex ion formation? Sa АОК во со DO Кур

Answer 1

Equilibrium constant for formation of a complex ion is represented by Kf .

Kb represents equlibrium constant for backward reaction.

Kd represents equilibrium constant for dissociation reaction.

Ksp represents equilibrium constant for solubility reaction.

Option A is correct.

When a soluble salt is added to a sparingly soluble salt having any common ion then equlibrium shifts. LeChatlier principle helps us to determine how this shift will happen.

For example , is common ion is in the product side then equilibrium will shift towards reactant side making sparingly soluble salt less soluble.

Since, KClO4 and NiCO3 have no common ion, addition of KClO4 will have no effect on the solubility of NiCO3.

Hence option D is true.
