Consider the insoluble compound zinc carbonate, ZnCO_3. The zinc ion also forms a complex with ammonia. Write a balanced net ionic equation to show why the solubility of ZnCO_3 (s) increases in the presence of ammonia and calculate the equilibrium constant for this reaction. For Zn(NH_3)_4^2+, K_f = 2.9 times 10^9. Use the pull-down boxes to specify states such as (aq) or (s). K = _____ Consider the insoluble compound zinc carbonate, ZnCO_3.
