Question:

Calculate the overall complex dissociation equilibrium constant for the Cu(NH3)42+ ion, given that  β4 for this complex is 2.1 x 1013.

Answer:

β4 = 2.1 × 1013

The overall complex dissociation equilibrium constant is the reciprocal of the overall stability constant, β4.

1/β4  = 1 / 2.1 × 1013

        = 4.7 x 10-14
