Define double salts and coordination compounds. Distinguish them with suitable examples.

Give examples of cis-trans isomerism exhibited by complexes of coordination number $4$ and $6$.

Define meridional isomer of a coordination compound.

Calculate the overall complex dissociation equilibrium constant for the $\mathrm{Cu}({\mathrm{NH}}_3{{)}_4}^{2+}$ ion, given that ${\mathrm{\beta }}_4$ for this complex is $2.1\times {10}^{13}.$

What do you understand by the stability constant, ${\mathrm{K}}_{\mathrm{s}}$ of a complex. Knowing that the value of ${\mathrm{K}}_{\mathrm{s}}$ for ${\left[\mathrm{Cu}{\left({\mathrm{NH}}_3\right)}_4\right]}^{2+}$ is $4.5\times {10}^{11}$ and for ${\left[\mathrm{Cu}{\left(\mathrm{CN}\right)}_4\right]}^{2-}$ is $2.0\times {10}^{27}$. Suggest (a) which complex species will furnish less ${\mathrm{Cu}}^{2+}$ ions in the solution. (b) which out of $\left({\mathrm{NH}}_3\right)$ and $\left({\mathrm{CN}}^{-}\right)$ is a stronger base?
