Which of the following statements is(are) correct?
(i) K_f is a measure of the interaction strength of a ligand relative to the interaction strength of the solvent molecules as a ligand.
(ii) The general trend in successive formation constants is K₁ < K₂ < K₃ < …. < K_n.
(iii) The dissociation constant is inverse of the formation constant.

Question

(i) Correct. The notation K_f represents a stepwise formation constant for a ligand binding to a metal ion, comparing the strength of interaction of the ligand to that of solvent molecules, indicating the relative binding affinity.(iii) Correct. The dissociation constant (Kd) is indeed the inverse of the formation constant (Kf), reflecting the equilibrium between the associated and dissociated states of a complex.
