The Copper Cycle Objective: To do multiple test that start out as copper and observe what happens after each one. Hypothesis: If you mix copper with certain chemicals, then it will change color. Materials: Copper powder Beakers Fume hood Nitric acid Stirrer Water Hot Plate Funnel Spatula Zinc Sodium Hydroxide Sulfuric Acid Tongs Safety Goggles Procedure: Get about .01 grams of copper powder Put the copper in a beaker and put into fume hood Add 2 mL of nitric acid and swirl it When you don’t see any more brown gas, remove beaker Put 25 mL of water in, then 2 mL of sodium hydroxide, look for solids forming Put hot plate on medium, put beaker onto hot plate and stir it, heat until solids appear Move beaker from hot plate to table…show more content…
Got a sample of copper Cu(s) orangish-brown fine powder Cu(s) solid copper powder The copper is in the beaker because the teacher put it there. Added nitric acid HNO₃(aq) brown gas blue liquid Cu(NO₃)₂(aq) copper nitrate In the blue liquid in the beaker. Added sodium hydroxide NaOH(aq) dark blue solid colorless liquid Cu(OH)₂(s) copper hydroxide In the blue solid inside of the beaker. Added heat (removes…show more content…
Then added 2 mL of Nitric acid, HNO₃(aq), which turned blue with copper, Cu(s), then made a brown gas, NO₂(g), when we covered the top. Then, added 25 mL of water , H₂O, and 2 mL of sodium hydroxide, NaOH(s), to the beaker, which turned to copper hydroxide, Cu(OH)₂(s). Next, put the beaker onto a hot plate, on medium, and stir with rod which causes dark brown algae substance to appear with black solids scattered around. Then, filter solution and solids got filtered out and only liquid was left. Added 15 mL of sulfuric acid, H₂SO₄(aq) to copper oxide, CuO(s) that turned to brown/black liquid then to copper sulfate, CuSO₄(aq), which was blue. Added .1 gram of zinc, Zn(s) to the 15 mL of sulfuric acid, H₂SO₄(aq) and copper oxide, CuO(s) that made the Zinc, Zn(s) bubbled while changing to copper, Cu(s), zinc, Zn(s) and 15 mL of sulfuric acid, H₂SO₄(aq). Finally, poured sulfuric acid, H₂SO₄(aq) out then added 10 mL of water, H₂O the poured out beaker, which turns the Zinc, ZnSO₄(aq) with tiny pieces of Copper powder, Cu(s). The finally results of copper that was left was .12 grams. During the lab .12 grams of copper was lost with -88%

    ratio of n-butyraldehyde and isobutyraldehyde is 3. The reaction processes at 0.7-3MPa and 80-120°C, when rhodium is used as the catalyst. The products ratio of n-butyraldehyde and isobutyraldehyde of 8-16 can be achieved. The catalysts of nickel or copper in gaseous phase or nickel in liquid phase are used for hydrogenation. Second process is aldol condensation, in this reaction; two molecules of acetic aldehyde condense by dehydration. The product crotonaldehyde is then transformed into n-butanol
