When ammonia is slowly added to a light blue solution of CuSO4 (aq), at first a white precipitate forms. What is the formula of that precipitate?
After more ammonia is added, a dark blue solution forms. What is the formula of the compound or ion responsible for the dark blue color?

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...

The deep blue compound Cu(NH3)4SO4 is made by the reaction of copper(II) sulfate and ammonia. CuSO4(aq) + 4NH3(aq) → Cu(NH3)4SO4(aq) If you use 47.0 g of CuSO4 and excess NH3, what is the theoretical yield of Cu(NH3)4SO4? If you isolate 38.2 g of Cu(NH3)4SO4, what is the percent yield of Cu(NH3)4SO4? ______ g Cu(NH3)4SO4 _______ %

Water is added to a group chloride precipitate and heated. The precipitate seems unaffected by heating The supernatant is separated from the precipitate while hot and treated with K2CrO4 (aq) but no precipitate forms. The white precipitate remaining from the first step is treated with NH3 (aq) and turns a grey/black color. When the ammoniacal supernatant is acidified with nitric acid, a white precipitate forms Sort the statements from the paragraph above into bins indicating what information the statement provided...
