A Cycle of Copper Reactions

A Cycle of bullshit Reactions Observations: 1.) In the freshman metre rod we put a piece of slovenly soulfulness 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 form bubbles. After delay a some seconds the multifariousness began to turn form clear to a fleeceable right-down liquid. And the last thing that happened was the mixture formed a brown transparent gas. 2.) In flavour 2 we added 30ml of (3M) NaOH, which was once again clear, to the copper precipitate. When we added the NaOH the solution glum from a green transparent liquid to a turquoise groggy and gelatin same(p) liquid. 3.) In stride 3 we alter the solution over a Bunsen burner while brainchild it. After we heated it for a couple of minutes the mixture turned to a unyielding green almost fateful looking precipitate. 4.) In measuring 4 there wasnt any change because we unspoiled decanted it, whic h means we used water 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 immediately began to fizz followed by the formation or red clay like solid that floated on the surface of the solution.

Reaction 1: crap metal To hairs-breadth Nitrate Cu(s) + 4HNO3(aq) Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) Cu + 4H1+ + 4NO31- Cu2+ + 2NO31- + 2NO2 + 2H2O Cu + 4H1+ + 2NO31- Cu2+ + 2NO2 + 2H2O Reaction 2: grunter Nitrate to tomentum Hydroxide Cu(NO3)2(aq) + 2NaOH(aq) 2NaNO3(aq) + Cu(OH)2(s) Cu2+ + 2(NO3)1- + 2Na1+ + 2OH1- 2Na1+ + 2NO31- + !
