1. A current of 5.02 A is passed through a Pb(NO3)2 solution. How long (in hours) would this current have to be applied to plate out 5.30 g of lead?
2. The voltage generated by the zinc concentration cell described by, Zn(s)|Zn2 (aq, 0.100 M)||Zn2 (aq, ? M)|Zn(s) is 16.0 mV at 25 °C. Calculate the concentration of the Zn2 (aq) ion at the cathode.
