$\left[ Cu \left( NH _{3}\right)_{3}\right]^{2+}+ NH _{3} \stackrel{ K _{4}}{\rightleftharpoons}\left[ Cu \left( NH _{3}\right)_{4}\right]^{2+}$
The value of stability constants $K _{1}, K _{2}, K _{3}$ and $K _{4}$ are $10^{4}, 1.58 \times 10^{3}, 5 \times 10^{2}$ and $10^{2}$ respectively. The overall equilibrium constants for dissociation of $\left[ Cu \left( NH _{3}\right)_{4}\right]^{2+}$ is $x \times 10^{-12}$ The value of $x$ is ...............
