Purpose – To measure the voltage of several voltaic cells and to determine the effect of concentration changes and complex ion formation non cell potential. To observe the quantitative relationship between amount of charge and amount of chemical change in an electrolysis process. Procedure - Refer to pages 113-117 and 128-130 in General Chemistry Volume 3 by Judith Casey and Robert Tatz, publishing by Hayden-McNeil Publishing, Inc. Report Sheet – See attached report sheets. Sample Calculations – See Attached Sheet Graph –None Report Questions – See Attached Sheet Conclusion: In Lab 28, the purpose was to measure the voltage of voltaic cells and determine the effect of concentration changes and complex ion formation. Different anodes and cathodes and their respective solutions were used in part A. The electrochemical apparatus was not plugged in for this experiment. The voltage for copper anode and copper cathode was .003 V, but should

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
