Consider the insoluble compound zinc carbonate, ZnCO_3. The zinc ion also forms a complex with hydroxide ions. Write a balanced net ionic equation to show why the solubility of ZnCO_3 (s) increases in the presence of hydroxide ions and calculate the equilibrium constant for this reaction. For Zn(OH)_4^2-, K_f = 2.9times10^15. Use the pull-down boxes to specify states such as (aq) or (s).
