4. Solid nickel carbonate (NiCO3) is pretty insoluble in water, as are many metal carbonates. But it is much more soluble in aqueous solutions of NaCN because nickel (II) reacts with cyanide anion to form a tetracyanonickelate complex. Nickel (II) is also mildly acidic, but you can ignore that part of the system if you want. A.) Write the balanced chemical equations AND the corresponding equilibrium constant expressions that explain the solubility behavior of nickel carbonate in aqueous 0.1 M NaCN. B.) Write the charge balance expression that applies to the BCE's you wrote above. C.) Write one mass balance expression for the system.
