Question

Equilibrium constants for Cd(II) and Cl complexes are given below. Calculate the concentrations of each cadmium species in water if Cd2+ = 10-8 M, and CF = 10-3 M. \mathrm{c}_{d}^{2+}+\mathrm{Cl}

\leftrightarrow \mathrm{CdCl}^{+} \quad \mathrm{K}_{1}=21 \mathrm{CdCl}^{+}+\mathrm{CF} \leftrightarrow \mathrm{CdCl}_{2}^{0} \quad \mathrm{~K}_{2}=8 \mathrm{CdCl}_{2}{ }^{0}+\mathrm{CF} \leftrightarrow \mathrm{CdCl}_{3}{ }^{-} \quad \mathrm{K}_{3}=\mathbf{1 . 2} \mathrm{CdCl}_{3}^{-}+\mathrm{Cl}^{-} \leftrightarrow \mathrm{CdCl}_{4}^{2-} \quad \mathrm{K}_{4}=0.35
