Consider the insoluble compound zinc carbonate, ZnCO3. The zinc ion also forms a complex with hydroxide ions. Write a balanced net ionic equation to show why the solubility of ZnCO3(s) increases in the presence of hydroxide ions and calculate the equilibrium constant for this reaction. For Zn(OH)42-, Kf
