Consider the insoluble compound iron(II) hydroxide, Fe(OH)2. The iron(II) ion also forms a
complex with cyanide ions. Write a balanced net ionic equation to show why the solubility of
Fe(OH)2 (s) increases in the presence of cyanide ions and calculate the equilibrium constant for this
reaction.
For Fe(CN)64, K₁= 7.7×1036. Be sure to specify states such as (aq) or (s).
