In an electrolysis cell similar to the one employed in this


1. In an electrolysis cell similar to the one employed in this experiment, a student observed the unknown metal anode lost .206g while a total volume of 84.90mL of H2 was being produced. The temperature in the lab was 230C and the barometric pressure was 621 mm Hg. Find the equivalent mass of this metal.

2. An oxidation-reduction happens in any electrochemical cell; voltaic or electrolytic.
a. Which half reaction occurs at the cathode in a voltaic cell?
b. Which half reaction occurs at the cathode in an electrolytic cell?
