# Calculate the overall complex dissociation equilibrium constant for

Question:

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

Solution:

β= 2.1 × 1013

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

$\therefore \frac{1}{\beta_{4}}=\frac{1}{2.1 \times 10^{13}}$

$=4.7 \times 10^{-14}$
