The following observations were collected during an Electrolytic Cells Lab, Metal Initial Mass (9) Final Mass (g) Change in Mass (g) Qualitative Data The carbon rod was all black at the start of the experiment. At the end of the Carbon 9.76 9.87 experiment, the section that was submerged in the solution of copper(II)ions had a bright reddish brown precipitate on it. The portion of the copper rod submerged in Copper Electrode12.07 11.96 0.11 the solution appeared to be less lustrous than the portion that was not submerged. 0.11 Does the data demonstrate the expected stoichiometric relationships for this system? Use the data to justify your answer Paragraph BEE
