Description Check out the attached documents. The lab document is attached.The pictures for the experiment is also attached. Please read them carefully. This is an informal lab report for Experiment 3 Qualitative Analysis of Electrolysis Reactions.Please write neatly and legibly. Part A: Preliminary observations Table 1: Tests for Cu2+ and SO3-2 What I Did Observations including before & after colors Positive test for Cu2+: 0.020 M CuSO4 + conc. NH3 Negative test for Cu2+: Distilled water + conc. NH3 Positive test for sulfite, SO3-2:0.1 M Na2SO3 + 0.2 mM KMnO4 Negative test for sulfite, SO3-2:Distilled water + 0.2 mM KMnO4 Part B: Qualitative Analysis of an Electrolytic Cell (Cu and Zn electrodes) Table 2: Observations and measurements What I Did What I observed or measured Conclusion(s) based on observation(s) or measurement(s) Observed Cu cathode Observed solution near Cu cathode Sulfite (SO32-) test Massed Zn anode before experiment (g) Massed Zn anode after experiment (g) Observed Zn anode Observed solution near Zn anode Question 1: Identify which of the reduction half-reactions (1A, 1B, 1C) occurs at the cathode.Your explanation is in the conclusion column of Table 2, so no need to defend answer. ____________ Question 2: Explain why the reduction of Zn (s) was not included as a choice. Think electron configuration. Question 3: Explain why the reduction of Cu (s) was not included as a choice. Think electron configuration. Question 4: Identify which of the oxidation half-reactions (2A or 2B) occurs at the anode. Your explanation is in the conclusion column of Table 2, so no need to defend your answer. ____________ Question 5: Explain why the oxidation of Zn2+ (aq) was not included as a choice. Think electron configuration. Question 6: Explain why the oxidation of SO42- (aq) was not included as a choice. (Hint: Draw the Lewis structure of SO42- to determine the oxidation number of the sulfur atom) Part C: Qualitative Analysis of an Electrolytic Cell (two Cu electrodes) Table 3: Observations What I Did What I observed Conclusion(s) based on observation(s) Observed color of solution before expt. Observed color of solution after expt. Observed Cu anode (“right” in diagram) Observed solution near Cu anode (“right” in diagram) Observed Cu cathode (“left” in diagram) Observed solution near Cu cathode (“left” in diagram) Flame test Cu2+ test Sulfite(SO32-) test undefined Question 7: Identify which of the oxidation half-reactions (3A or 3B) occurs at the anode.Your explanation is in the conclusion column of Table 3, so no need to defend your answer. ____________ undefined undefined Question 8: Identify which of the reduction half-reactions (4A or 4B) occurs at the cathode.Your explanation is in the conclusion column of Table 3, so no need to defend your answer. __________ undefined undefined undefined undefined Question 9a. Using the half-reactions in your answers to questions 1 & 4, write the net cell reaction for the Zn-Cu electrolytic cell. Show both half-reactions and the net call reaction in your answer. Be sure the # of electrons are the same in the 2 half-reactions before adding them. undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined Question 9b. Using the half-reactions in your answers to questions 7 and 8, write the net cell reaction for the Cu-H+ electrolytic cell. Show both half-reactions and the net call reaction in your answer. Be sure the # of electrons are the same in the 2 half-reactions before adding them.
