Calculate the overall complex dissociation equilibrium constant for the ion [Cu(NH3)4]2 + , given that β4 for this complex is 2.1×1013.

given: β4 = 2.1×1013

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

⇒  1/( β_4 )  =  1/〖2.1×10〗^13 

⇒ The overall complex dissociation equilibrium = 4.7×10-14
