stability constants

Question

A high value of formation constant (K) indicates:

RankGuru · Accepted Answer

The **Formation Constant ($K_f$ or $\beta_n$)** represents the equilibrium of complex formation:
$M + nL \rightleftharpoons [ML_n], \quad K_f = \frac{[ML_n]}{[M][L]^n}$
- A **large value of $K_f$** means that at equilibrium, the concentration of the complex is much higher than that of free metal ions and ligands.
- This signifies a highly stable complex. Conversely, $K_d$ (dissociation constant) is $1/K_f$; a low dissociation constant indicates high stability.
