Lecture 9: Cell Potentials • Reading: Zumdahl 11.2 • Outline – What is a cell potential? – SHE, the electrochemical zero. – Using standard reduction potentials. Cell Potentials In our galvanic cell, we had a species being oxidized at the anode, a species being reduced at the cathode, and electrons flowing from anode to cathode. The force on the electrons causing them to full is referred to as the electromotive force (EMF). The unit used to quantify this force is the volt (V) 1 volt = 1 Joule/Coulomb of charge V = J/C Cell Potentials (cont.) We can measure the magnitude of the EMF causing electron (i.e., current) flow by measuring the voltage. Anode Cathode e - 1/2 Cell Potentials What we seek is a way to predict what the voltage will be between two 1/2 cells without having to measure every possible combination. To accomplish this, what we need to is to know what the inherent potential for each 1/2 cell is.

    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.
