A voltaic cell consists of a strip of lead metal in a solution of Pb(NO3)2 in one beaker, and in the other beaker a platinum electrode immersed in an NaCl solution, with Cl2 gas bubbled around the electrode. The two beakers are connected with a salt bridge.
(I) Which metal is at the anode?
(II) Which electrode loses mass?
(III) What is the cell potential under standard conditions?
