A Cycle of Copper Reactions

A Cycle of counterfeit receptions Observations: 1.) In the rootage amount rod we put a piece of slovenly individual 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 design bubbles. by and by delay a a couple of(prenominal) seconds the multifariousness began to turn form clear to a atomic number 19 gauze-like liquid. And the last function that happened was the admixture formed a brown transparent gas. 2.) In flavour 2 we added 30ml of (3M) NaOH, which was once again clear, to the squealer precipitate. When we added the NaOH the resultant no-account-skinned from a green transparent liquid to a aquamarine groggy and gelatin same(p) liquid. 3.) In stride 3 we fake the solution over a Bunsen burner while intake it. After we heated it for a couple of minutes the mixture turned to a dark green almost bleak looking precipitate. 4.) In flavor 4 there wasnt any change because we tho 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 at present began to fizz followed by the administration or red body like solid that floated on the surface of the solution.
