Solid ammonium carbonate is slowly added to 125 mL of a iron(II) acetate solution until the concentration of carbonate ion is 0.0233 M. What is the maximum amount of iron(II) ion remaining in solution? Consider the insoluble compound silver bromide, AgBr The silver ion also forms a complex with cyanide ions. Write a balanced net ionic equation to show why the solubility of AgBr (s) increases in the presence of cyanide ions and calculate the equilibrium constant for this reaction. For Ag(CN)_2, K_f = 5.6 times 10^18.
