In experiment 7, when concentrated ammonia is added to acidic copper solution, the pale-blue precipitate forms, followed by formation of bright blue soluble compound. Write formulas of the precipitate and of colored complex. When potassium iodide is added to copper(II) nitrate solution, a brown precipitate forms. Write and balance the corresponding reaction equation. This brown precipitate is titrated with sodium thiosulfate solution. Write and balance the corresponding equation. After titration, a white precipitate is left in the solution. Write the...

When NH3 is added to a solution that contains Cu2+ ions at first the solution becomes cloudy and a white precipitate starts to fall to the bottom of the container. If NH3 continues to be added the solution changes from a light blue color to a dark blue color and the precipitate disappears. Describe what is happening is happening on the molecular level.

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.

1. I placed 5 mL of 0.025 M CuSO4 in a test tube, and slowly added 15 M NH3 until my solution turned blue, I then removed reactant by adding (CuSO4, NH3, H20, HCl, NaOH) and my test tube appeared clear, light light blue. That's because as I removed reactant, the Cu2+ concentration (increased, decreased, stayed the same) 2. In a medium test tube, I added 2 drops of 6 M NaOH to 5 mL of 0.05 M MgCl2(aq) to...
