Lab #18 Stoichiometry In this lab, we reacted aluminum foil with a copper chloride solution, and determined the amount of metal that should be produced, given the amount of aluminum used. First, we obtained a piece of aluminum with a mass of 0.809 g, and reacted it with 100 mL of Copper II Chloride, after heating the solution. Then, we filtered out the copper separated in the reaction using filter paper, massing 0.751 g. Once all the solution was filtered, we massed the new filter paper filled with copper, after letting it dry overnight. The mass of the filter paper with the copper was 3.450 g, making the mass of just the copper 2.699 g. This closely compares to the accepted mass of copper for this reaction of 2.88 g. Finally, we found the…
This is inaccurate as it should have been 1:1 ratio of moles of copper produced to moles of iron used because the law of conservation of mass states that the mass of substances produced by a chemical reaction is always equal to the mass of reacting substances. But in my opinion, I think I did a good job of making it even without even noticing! It was a close call.…

Reaction 1, we start with 0.503 g copper metal that dissolves in 5.0 mL of concentrated nitric acid. This is an example of redox as a transfer of electrons is occurring. The second part of the reaction allows the nitrate ion to oxidize the copper. Reaction two, while stirring 20 mL of 6.0 M NaOH was added to the flask. Hydroxide ion binds to the copper (II). This is an example of metathesis as the cations and anions exchange partners. Reaction Three, Heating the copper hydroxide to a medium boil on the hotplate while occasionally stirring produces copper oxide. Heating allows for decomposition. It also allows the copper to oxidize. 50 mL of hot water was added three times and then decanted the supernatant solution. Reaction 4, Copper oxide is dissolved with 5 mL of 6.0M Sulfuric Acid. This allows the Oxygen to bind with to water and allow the Copper (II) ion to reform. Reaction 5, 1.0 g of 30-mesh Zinc is added. Start with half and add remain half of zinc until solution lacks the blue hue. Followed by adding 10 mL of concentrated HCl. This should eliminate the zinc through gas form decant the liquid and heat until copper is dry. Weigh out the flask + copper. Then determine the percent…
The purpose of this lab was to find out the reaction of iron nails and CuSO4, copper sulfate solution. Before starting the experiment, there were two possible outcomes of the reactions. CuSO4 + Fe → FeSO4 + Cu or 3CuSo4 + 2Fe → Fe2(SO4)3 + 3Cu. The ion chart showed that iron can only make two charges, +2 and +3.…
