CBSEENCH12007312

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

Solution
we have given:
β4 = 2.1 × 1013 
 
The overall dissociation constant is the reciprocal of overall stability constant i.e.,

1/B
4 = 1/2.1 x1013 

       = 4.7 x 10
–14.
