Unformatted text preview: Reasonable explanations for discrepancies between measured and calculated cell potentials. (1 points) Pre/Post Lab Questions as assigned by your TA (0-2 points) Lab Tips Experiments #9 Keep the alligator clips dry. Keep the alligator clips dry. Keep the alligator clips dry. Keep the alligator clips dry. For each measurement, record ANODE CATHODE VOLTAGE All measured galvanic cell potentials are positive. The iron wire electrode has an enamel coating and ~1/4 inch must be scraped off at each end. Looking good in Physics 101 The negative lead of the voltmeter (marked –COM or ± ) should be connected to the anode of the cell so that only positive voltages are displayed. Use a battery to practice taking voltage measurements so that you can recognize the anode and the cathode for the common cell types....
