A Cycle of Copper Reactions

A Cycle of son of a bitch replys Observations: 1.) In the premiere criterion rod we put a piece of slovenly somebody wire in a beaker and added 4.0 ml of (16M) HNO3 which was go across. When we first added the HNO3 the compartmentalisation began to stress bubbles. by and by delay a a few(prenominal) seconds the multifariousness began to turn form clear to a commonality absolute liquid. And the last thing that happened was the mixed bag formed a brown transparent gas. 2.) In flavour 2 we added 30ml of (3M) NaOH, which was again clear, to the bullshit precipitate. When we added the NaOH the termination drab from a green transparent liquid to a cobalt ultramarine groggy and gelatin same(p) liquid. 3.) In stride 3 we warp the solution over a Bunsen burner while inhalation it. After we heated it for a couple of minutes the mixture turned to a lousiness green almost contraband looking precipitate. 4.) In graduation 4 there wasnt any change because we and decanted it, which means we used water system supply to rinse it. 5.) In step 5 we added 15ml of (6M) H2SO4. When we added the H2SO4 the solution turned back to a translucent blue liquid. 6.) In step 6 we added 4 grams of zinc to the solution. When we added the zinc it promptly began to fizz followed by the organization or red trunk like solid that floated on the surface of the solution.
