Suppose we construct a galvanic cell by placing two identical platinum electrodes in two beakers that are connected by a salt bridge. One beaker contains 1.0 M HCI, and the other a 0.010 M solution of Na;SO. at pH 7.00. Both cells are in contact with the atmosphere, with PO2PO2 = 0.20 atm. If the relevant electrochemical reaction in both compartments is the four-electron reduction of oxygen to water: Ozg) + 4H* (aq) + 4e - 2H20() What will be the potential when the circuit is closed?

The mass of three different metal electrodes, each from a different galvanic cell, were determined before and after the current generated by the oxidation-reduction reaction in each cell was allowed to flow for a few minutes. The first metal electrode, given the label A, was found to have increased in mass; the second metal electrode, given the label B, did not change in mass; and the third metal electrode, given the label C, was found to have lost mass. Make an educated guess as to which electrodes were active and which were inert electrodes, and which were anode(s) and which were the cathode(s).
