A Study of Electrolysis and Faraday’s Laws Purpose : The purpose of Experiment 20 is to use two aqueous electrolysis cells, one composed of copper and the other of H 2 and O 2 gas, and the results will be used with Faraday’s Laws to calculate the volume of the hydrogen generated in the second cell. Procedure: 1. Set up the apparatus as shown in figure 20-1 and placed close to the sink so an aspirator can be used to remove water from the bowl. Fill a 100mL beaker about ¾ of the way with Na 2 CO 3 . Place this in a stainless steel beaker and fill to about one inch from the top with tap water, and then place the beaker in a plastic bowl. 2. Remove the wire from the rubber stopper on the carbon electrode to inspect it and sand the wires if necessary. Replace the wire and firmly press the carbon electrode into the top of the rubber stopper. Make sure the exposed wire and the carbon electrode are making contact and the electrode is secure in the stopper. Place the wire mesh screen over the carbon
