Hey. I was wondering if someone could fill out this chart for me.
PRE-LABORATORY QUESTIONS
Using the table of standard reduction potentials found on page 6, determine the cell potential for the following combination of electrodes.
Calculate the potential, Eocell, for a Copper-Gold cell
1. Students should indicate which metal is the cathode & anode E°cell = E°Au - E°Cu 10 @ 0.3 pts
2. Student need to show the assigned potential with their proper signs E°cell = 1.42 v -(0.34 v) 10 @ 0.6 pts
3 The value for Eocell = 1.08 v Answer 10 @ 0.1 pts
To receive full credit on a calculation all three steps must be shown
