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 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?
40. Concentrated aqueous ammonia is added to a solution of copper(II) sulfate. A white precipitate forms. The precipitate dissolves as more ammonia is added, generating an intensely blue solution. Which combination of net ionic equations, in the appropriate order, describes this chemistry?! I Cu?* (aq) + 2OH(aq) Cu(OH)2 (19) II Cu?" (aq) + 2OH(aq) = Cu(OH)2 (8) III Cu(OH)(aq) + 4 NH, (aq) Cu(NH3),?* () + 2OH(aq) IV Cu(OH)2 (8) + 4NH, (aq) Cu(NH3)*(14) + 2OH(aq) V NH3(aq) + H20...
When potassium iodide is added to copper(II) nitrate solution, a brown precipitate forms. This brown precipitate is titrated with sodium thiosulfate solution. After titration, a white precipitate is left in the solution. Write the formula of this precipitate.
When potassium iodide is added to copper(II) nitrate solution, a brown precipitate forms. This brown precipitate is titrated with sodium thiosulfate solution. Write and balance the corresponding equation.
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.
When potassium iodide is added to copper(II) nitrate solution, a brown precipitate forms. Write and balance the corresponding reaction equation.
You dissolve a small amount of your copper product in a few mL of water. When you added eight drops of 6 M HCl to the copper complex, you observe that the bright blue color fades and no precipitate forms. Write a net ionic equation for any reaction taking place. Is this compound resistant to attack by acid? How can you tell? If it is helpful, the reaction involved in the experiment is: Cu(H2O)42+ (aq) + SO42- (aq) + 4NH3...

Put these in order in how to safely light...
In an ammonia solution, the silver ion, Ag, forms the colorless, but soluble diamminesilver(I) complex ion, Ag(NH3)2. If ammonia is added to a solution that contains an AgCI precipitate, the solid dissolves completely. Write a net-ionic equation for the equilibrium involved and explain the shift that takes place. Choose the best answer. AgCl(s) +2 NH3(a)Ag(NH3)2 (aa) C(aq) Adding ammonia to AgCl(s) dissolves the solid by displacing chloride ions with ammonia molecules, forming a soluble complex ion Ag (a2 NH3(aq) Ag(NH32...
