Solution
Correct Answer:
Stable complex
The Formation Constant (Kf or βn) represents the equilibrium of complex formation: M+nL⇌[MLn],Kf=[M][L]n[MLn]
- A large value of Kf 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, Kd (dissociation constant) is 1/Kf; a low dissociation constant indicates high stability.
This easy difficulty chemistry question is from the chapter coordination compounds, covering the topic of stability constants. It appeared in the 2025 exam.
