In part A of Expt. 10, we were going to construct some simple galvanic cells. The first cell to be constructed consisted of Cu and Pb electrodes placed in 0.10 M solutions of Cu(NO3)2 and Pb(NO3)2 . Which electrode do you expect to be the anode and which would be the cathode? Explain. Can a galvanic cell have a negative cell potential? What should you do if you measured a negative cell potential when the two half-cells in a galvanic...
