When ammonia is added to Zn(NO3)2 solution, a white precipitate forms, which dissolves on the addition of excess ammonia; but when ammonia is added to a mixture of Zn(NO3)2 and NH4NO3 no precipitate forms at any time. Suggest an explanation for this difference in behavior.

Explain in terms of ion concentrations and Ksp why a precipitate forms for some solutions. When ammonia is added to a solution that has Cu(OH)2(s) precipitate in it, the precipitate dissolves. Use Le Châtelier’s principle to explain this. Based on your observations, when a colour change occurs but no phase change occurs, what kind of reaction might have occurred?

1. If a solution of hydrochloric acid is added to a solution of sodium carbonate, what is observed? Write the net ionic equation of any reaction that may occur (4P). 2. You have a clear colorless unknown solution with a group I cation. After adding some hydrochloric acid solution you obtain a white precipitate. Addition of ammonia causes the white precipitate to dissolve. Acidifying with nitric acid makes the precipitate reappear. Which cation do you suggest was in the unknown...
