Suppose you work for an environmental laboratory and you want to use an electrochemical method to measure the concentration of Pb in groundwater. You construct a galvanic cell using a standard oxygen electrode in one compartment (E cathode = 1.23 V). The other compartment contains a strip of lead in a sample of groundwater to which you have added sufficient acetic acid, a weak organic acid, to ensure electrical conductivity. The cell diagram is as follows" Pb(s) IPb"(aq, ? M)IH"(aq), 1.0 MIO:(g, 1.0 atm)|Pt(s) When the circuit is closed, the cell has a measured potential of 1.62 V. Determine the concentration of Pb" in the groundwater
