We explored one such reaction in lecture when we combined zinc with nitric acid. The sequence begins with copper metal and ends with copper metal, so it is called a cycle of copper reactions. The original copper sample contained a specific number of moles of copper, and that amount of copper was present in every reaction, precipitate, and solution. Suppose you start with 0.514 g of Cu. Here is some background information so you will understand the chemistry behind the reactions you will perform.

Reaction 1 is a redox reaction because it involves oxidation of Cu solid to Cu (II) ion and reduction of the nitrate ion to gaseous nitrogen dioxide. This is a cycle of reactions, because you start and end with the same substance, copper metal. a) The copper was not completely dry. The aluminium foil appears unable to displace copper from copper(II) sulfate solution. • With careful attention to quantitative lab practices, you should be able to recover all the copper you started with. Mass of the substance, m = 75.0 g The last reaction returns the copper to its original metallic form which you will recover and weigh. The percent recovery came out to be 17%. 3. 3 CuSO 4 (aq) + 2 Al(s) Al 2 (SO 4) 3 (aq) + 3 Cu(s) This reaction is an example of a redox reaction: where aluminum is oxidized and copper is reduced. %PDF-1.5 %���� Write a balanced equation for this reaction. When I do this with my students, we start with copper pennies, and end up with "mossy" copper. In the beaker with the solid copper is a dissolved solution of zinc sulfate.

Often side reactions, Substance with pH < 7 are acids Suppose you start with 0.493 g of Cu. This indicates that silver ion has a vacant orbital at lower energy than that in which two of copper's electrons reside. Observations will be made for each reaction. After performing all the reactions, you have 0.466 g of Cu. Redox couples are written "ox/red". Weight of SO3 is 61.5 g. In total, you will perform five reactions involving copper, starting with the oxidationof copper metal to copper ion and ending with the reductionof copper ion to … Median response time is 34 minutes and may be longer for new subjects. Beginning with pure copper at the top of the figure, these are: Reaction 1: Oxidation of metallic copper with nitric acid (HNO 3). The original copper sample contained a specific number of moles of copper, and that amount of copper was present in every reaction, precipitate, and solution. Copper is oxidized using an acid which results in the loss of electrons. You should, Answers: 1. ... That’s why it is better to give examples or explanations related with this property. CHEMICAL REACTIONS OF COPPER AND PERCENT YIELD KEY Objective To gain familiarity with basic laboratory procedures, some chemistry of a typical transition element, and the concept of percent yield.

PART A: 1. You will carry out the Copper Cycle using the ordering you created in discussion. The atomic theory predicts this behavior. In this example, copper donates electrons (is oxidized). The balanced equation is: The cycle of copper reactions starts with solid copper metal and ends with solid copper metal. In the sequence the available starting materials change in a number of steps. First - the reaction of copper with (concentrated) nitric acid is exothermic. Then sodium chloride is added and dissolved. Preparation of Cu (OH)2. Start studying CHEM 1212: Exp. That all depends on what the copper looked like at the beginning. In this lab you will weigh a sample of copper metal and react it with nitric acid to form copper(II)nitrate. The four-reaction copper cycle featured in this experiment is summarized below. Copper Cycle Chemists in industry often use stepwise procedures involving a sequence of chemical reactions to obtain a desired product. [72] Experiment 6: The Reactions of a Copper Cycle PURPOSE AND LEARNING OBJECTIVES During the process of this experiment, you will observe and record the chemical and accompanying physical changes that occur when metallic copper is carried through a series of chemical reactions that produce a number of different copper compounds before the copper is restored to its original metallic state.

The amount of copper recovered at the end of the four-reaction cycle provides a good test of laboratory technique and efficiency. Start studying CHEM 111: Experiment 3 - The Copper Cycle. Also, my reactions seemed to take a very long time, particularly the reaction of the copper with zinc. The cycle of copper reactions starts with solid copper metal and ends with solid copper metal. Don't use plagiarized sources. The sequence begins and ends with copper metal, so it is called a cycle of copper reactions. I had to apply heat during the first reaction of the copper wire with HNO3 because some of the wire still remained. THE COPPER CYCLE: A Series of Reactions . Copper(I) sulfide is a copper sulfide, a chemical compound of copper and sulfur. The addition of sulfuric acid to the copper (II) oxide will produce copper (II) sulfate. What kind of reaction is this? In other words, to recover the same amount of copper metal that you started with, this will require careful work. Note: The following reactions involved in the Copper Cycle are in random order. endstream endobj startxref 18 copper … The cycle of copper reactions starts with solid copper metal and ends with solid copper metal. What percentage of the copper did you recover? These masses differ quite tremendously. View Lab Report - Copper Cycle Pre-Lab from CHEM 110 at McGill University. Sulfur when heated becomes red because of its phase transition (from solid to liquid), and later it reacts with copper in a pretty simple reaction:Cu + S --> CuS . Cu(s) CuC12(aq) 3. This is roasted in air to give black copper (II) oxide, which can be redissolved to regenerate the starting solution of copper (II) sulfate. THE COPPER CYCLE: A Series of Reactions . It is found in nature as the mineral chalcocite. Now aluminium is more reactive because it displaces copper. From this blue solution, you will precipitate copper(II) hydroxide.   Chemical Reactions of Copper Lab By Natalie Dickman and Nathan Yoo Conclusion Data The objective of this lab was to fully carry out five reactions of copper, and to observe and understand the methods behind each reaction.

Two iron nails that were cleaned by rubbing with sand paper were immersed into test tube B and left undisturbed for 20 min. Remind students what copper looks like, so that they know what they are looking for. Reaction Specific Guidelines for Reaction ; Cu(s) + HNO 3 (aq) → This reaction must be performed in the back of a fume hood. CYCLE OF COPPER REACTIONS. Copper also forms an important series of alloys with aluminum, called aluminum bronzes. b) The "copper" you recovered wasnt pure and contained one of the intermediate copper complexes (nitrate,hydroxide,etc.) Initial temperature, T1 = 25 oC Thus, the same number of moles of copper was produced in the final reaction because the amount of copper remained constant throughout the experiment. Second - the maximum possible yield (note correct spelling) is 100%, which. This is a good example of disproportionation - a reaction in which something oxidises and reduces itself. Apparatus and Chemicals 0.5 g piece of no. Because no copper is added or removed between the initial and final steps, and because each reaction goes to completion, you should be able to quantitatively recover all of the copper you started with if you are careful and skillful. The cycle of copper reactions to be performed in this experiment.
