AFormation constant Kf
BSolubility product Ksp
CIonisation constant Ka
DDissociation constant Kd
Answer & Solution
Correct answer: D. Dissociation constant Kd
1. Reversing a reaction reverses the constant that describes it.
2. Forming a coordination complex is described by the formation constant Kf.
3. Alternatively, the reverse reaction can be considered.
4. That reverse reaction is the decomposition of the complex ion.
5. In that case the equilibrium constant is a dissociation constant, written Kd.
