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.

The solubility of COCO3 is measured and found to be 1.03x10-4 g/L. Use this information to calculate a Ks value for cobalt(II) carbonate. Ksp
A solution containing a mixture of metal cations was treated with dilute HCl and no precipitate formed. Next, H, S was bubbled through the acidic solution. A precipitate formed and was filtered off. Then, the pH was raised to about 8 and H,S was again bubbled through the solution. A precipitate again formed and was filtered off. Finally, the solution was treated with a sodium carbonate solution, which resulted in no precipitation. Classify the metal ions based on whether they were definitely present, definitely absent, or whether it is possible they were present in the original mixture.

3. To verify the existence of silver in your solution, one should first form a white precipitate by addition of NaCl. Next, the precipitate should dissolve in aqueous ammonia. Silver can re- precipitate by addition of 6M HNO,. Using chemical equations, describe the identity of the product formed in each step. E (Your three steps should be after addition of NaCl, after addition of ammonia and after addition of HNO,.) 3° 3° it in mirod with sodium chloride
a. What cations may be present in a pale blue solution that turns deep blue and forms a white precipitate upon 6M NH3(aq)? b. A white solid dissolves in water to form a neutral solution. No precipitate forms when the solution is treated with a solution of NH4Cl/ NH3 buffer, nor when (NH4)2S is added. When the solution is acidified with HC2H3O2 and K2CrO4 is added a yellow precipitate forms. This precipitate dissolves upon addition of concentrated HCl. Acidification of a solution of the solid with HNO3 followed by addition of AgNO3 causes formation of a white precipitate. What is the identity of the original solid?
