Find the oxidation state of the cobalt in these complex ions.
State the two reaction types involved when the cobalt ions form these complex ions.
The complex $[\text{Co(NH}_3)_4\text{Cl}_2]^+$ exhibits isomerism. Draw the three-dimensional structures of the two isomers, and indicate the type of isomerism present.
What does the term co-ordination number mean?
Complete the table by predicting suitable co-ordination numbers, formulae and charges for complexes C, D, E and F.
Write the expressions for the stability constants, $K_{\text{stab}1}$ and $K_{\text{stab}2}$, for these two equilibria. Include units in your responses.
An equilibrium may exist between these two complexes, as shown in equilibrium 3. Write an expression for $K_{\text{eq}3}$ in terms of $K_{\text{stab}1}$ and $K_{\text{stab}2}$.
The stability constants are given as follows: $K_{\text{stab}1} = 1.4 \times 10^2$, $K_{\text{stab}2} = 8.0 \times 10^{-2}$. Calculate the value of $K_{\text{eq}3}$ and include its units.
