The values of dissociation constants of [Cu(NH_(3))_(4)]^(2+) and [Co(NH_(3))_(6)]^(3+) are 1.0xx10^(-12) and 6.2xx10^(-36) respectively. Which complex would be more stable and why ?

Answer»

SOLUTION :Smaller the value of the dissociation constant, more stable is the COMPLEX in the solution. Hence, `[Co(NH_(3))_(6)]^(3+)` is more stable than `[Cu(NH_(3))_(4)]^(2+)` ion.
