1. In an electrolysis cell similar to the one employed in this experiment, a student observed that his unknown metal anode lost 0.238 g while a total volume of 94.50 mL of H2 was being produced. The temperature in the laboratory was 25°C and the barometric pressure was 740. mm Hg. You will need to look up vapor pressure of water at that temperature. Find the equivalent mass of this metal.
2. An oxidation-reduction happens in any electrochemical cell; voltaic or electrolytic. (look these terms up in your general chemistry text if you don't remember them.)
a. Which half reaction occurs at the anode in a voltaic cell?
b. Which half reaction occurs at the anode in an electrolytic cell?
3. A. Which the reduction reaction for elemental sulur that gains two electrons to form the sulfide ion.
B. Write the oxidation reaction for copper metal losing two electrons to form the copper II ion.
