Question
Which of the following complexes formed by $Cu^{2+}$ ions is most stable?
✓
Answer
The stability of complexes is represented by the magnitude of its "Stability constant $(K)".$ A higher value of stability constant of certain complex denotes its greater stability. Mathematically, the same hols good for $\log K$ values. Among the given $\log K$ values of different complexes, it is noted that the $\log K$ value for complex at $(ii)$ is maximum $(ie = 27.3).$ Hence it is most stable.
