ADissociation constant Kd
BIonisation constant Ka
CFormation constant Kf
DSolubility product Ksp
Answer & Solution
Correct answer: C. Formation constant Kf
1. Complex formation has its own equilibrium constant.
2. A metal ion reacts with one or more ligands to form a coordination complex.
3. The equilibrium constant for that reaction is called a formation constant, written Kf.
4. It is sometimes called a stability constant.
