**Nickel(II) Hydroxide and Complex Formation with Cyanide Ions**

Consider the insoluble compound nickel(II) hydroxide, \( \text{Ni(OH)}_2 \). The nickel ion also forms a complex with cyanide ions. Write a balanced net ionic equation to show why the solubility of \( \text{Ni(OH)}_2 \) (s) increases in the presence of cyanide ions and calculate the equilibrium constant for this reaction.

For \( \text{Ni(CN)}_4^{2-} \), \( K_f = 1.0 \times 10^{31} \). Be sure to specify states such as (aq) or (s).

**Equation Boxes:**

\[ \text{[Box for reactant] (state)} + \text{[Box for reactant] (state)} \rightarrow \text{[Box for product] (state)} + \text{[Box for product] (state)} \]

\[ K = \text{[Box for equilibrium constant expression]} \]

*Note: Fill in the boxes with the appropriate chemical formulas and states (aqueous or solid).*
