Zinc is in solid state and copper sulfate in aqueous statePredicted Types of Reaction. Single-displacement reactionObservations of Products. Copper is in solid.
CopperII oxide and copper carbonate. Such reactions are considered acid-base reactions. Copper sulfate most occurs in nature as the pentahydrate CuSO45H2O.
This mineral is called chalcanthite. Where To Download Chemical Reactions Of Copper Lab Answers chemical producers and regulatory enforcers without the confrontation which often characterizes such interactions -Martyn Poliakoff Green Chemistry February Its is an introductory text taking a broad view. Calculate the mass of copper recovered.
Use three decimal places in your answer. - Mass of the clean dry empty evaporating dish in step 10. - Mass of the evaporating dish PLUS the recovered copper in step 16.
- Mass of recovered copper at the end of the procedure. In the Copper Lab and based on the Law of Conservation of Mass the amount of copper obtained at the end of the experiment should be less than equal to greater than the amount of copper at the beginning of the lab. In the word equation hydrogen oxygen water hydrogen is a reactant product and water is a reactant product.
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. The copper first underwent a redox reaction with nitric. Fundamental types of chemical re actions called redox reactions and metathesis reactions.
By means of these reactions you will carry out several chemical transformations involving copper and you will finally recover the copper sample with maximum efficiency. The chemical reactions involved are the following. Cus 4HNO 3aqÆ CuNO 3.
The balanced chemical formula of reaction 4 was CuO sH2SO4 aq CuSO4 aq H2O l and was an acid-base reaction. The balanced formula for reaction 5 was CuSO4 aq Zn s ZnSO4 aq Cu s and was an oxidation-reduction reaction. Initial and Final Copper Masses.
Mass of Copper g 0479 g. The main chemical concept that this lab involves is the Law of Conservation of Mass. This states that in a chemical reaction matter can neither be created or destroyed or more simply the mass of the products must equal the mass of the reactants.
In this lab we tested this by putting copper through five different reactions and many phase. The dissolution of copper metal requires a solution containing what. Nitration ions and hydrogen ions.
The balance equation of the dissolution of copper metal. Cus 4HNO3aq - CuNO32 aq 2NO2g 2H2Ol after you dissolve coper metal what are we doing. The reaction involving copper is an example of an oxidation reaction.
When an element increases in charge it is said to be oxidized. In solution most ions are colorless. CopperII ion however is an exception.
Questions Based on the background information and your observations answer the following questions before continuing. The sequence begins with copper metal and ends with copper metal so it is called a cycle of copper reactions. Observations will be made for each reaction.
Since no copper is added or removed between the initial and final reaction steps copper can be quantitatively recovered. Transcribed image text. Post-Lab Lab 4 - A Cycle Of Chemical Reactions Of Copper A Cycle Of Chemical Reactions Of Copper Are you completing this experiment online.

The Copper Lab demonstrates stoichiometry in chemistry. Stoichiometry is helpful in calculating the amount of an element or compound in chemical reactions. For the lab stoichiometry was used to predict the amount of copper that would be left over.
Using stoichiometry the experimenter could find out that the product of the copper would have. Copper oxide dissolves in acid regenerating the copper II ion which once again binds to waterCuO s 2 H 3 O aq 3 H 2 O l – CuH 2 O 6 2 aq Finally zinc metal reduces the hydrated copper II ion back to metallic copper while itself turning being oxidized to zinc II ions. We have seen this reaction before in the copper chloride lab.
Fundamental types of chemical reactions like those described in Experiment 4redox reactions and metathesis reactions. By means of these reactions you will carry out several chemical transformations involving copper and you will finally recover the copper sample with maximum efficiency. The chemical reactions involved are the following.
The TA will contact you or your lab group regarding your copper yield. This data will be used to complete the assignment. Experiment 4 is broken up into five main reactions and 2 side reactions that may be asked on quizzes.
Cu s HNO 3 aq Cu NO 3 2 aq H 2 O l NO 2 g HNO 3 is a strong acid. CHEM 1411 Reactions of Copper Lab Objectives. To observe the reactions of copper and its compounds 2.
To calculate the percent recovery of copper undergoing a series of reactions Materials. Graduated cylinders Beakers Cu wire Za metal Concentrated HNO Acetone 3 NH 1 6 MHSO Deionized water Hot plate Introduction. In general there are five types of chemical.
Is a cycle of reactions because you start and end with the same substance copper metal. In the first reaction copper metal is oxidized by nitric acid to form copper II nitrate CuNO 3 2. It is then converted to copper II hydroxide CuOH 2 by reaction with base.
When this compound is heated it is transformed to copper II oxide CuO. Copper II oxide is then reacted with acid to form copper II.
