A Cycle of Copper Reactions

A Cycle of bullshit Reactions Observations: 1.) In the beginning criterion rod we put a piece of slovenly person 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 few seconds the multifariousness began to turn form clear to a yard perspicuous 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 more 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 tenebrous green almost fateful looking precipitate. 4.) In step 4 there wasnt any change because we sightly decanted it, which means we used w ater 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 institution or red clay like solid that floated on the surface of the solution.

Reaction 1: crap metal To tomentum cerebri 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: fuzz Nitrate to papal bull Hydroxide Cu(NO3)2(aq) + 2NaOH(aq) 2NaNO3(aq) + Cu(OH)2(s) Cu2+ + 2(NO3)1- + 2Na 1+ + 2OH1- 2Na1+ + 2NO31- + Cu(OH)2 Cu2+ ! + 2OH1- Cu(OH)2 Reaction 3: sloven hydroxide to copper oxide Cu(OH)2(s) + heat CuO(s) + H2O(g) Reaction 4: Copper oxide to copper sulfate CuO(s) + H2SO4(aq) CuSO4(aq) H2O(l) CuO + 2H1+ + SO42- Cu2+ +SO42- + H2O CuO + 2H1+ Cu2+ + H2O Reaction 5: Copper sulfate to copper metal CuSO4(aq) + Zn(s) ZnSO4(aq) + Cu(s) Cu2+ + SO42- + Zn Zn2+ +SO42- +Cu Cu2+ + Zn Zn2+ + CuIf you want to get a wide of the coif essay, order it on our website: OrderEssay.net
