Question 1

What type of compound can form a layer of protection against corrosion?


Question 2

A cell is set up with copper and lead electrodes in contact with CuSO4(aq) and Pb(NO3)2(aq), respectively, at 25°C. The standard reduction potentials are:

              Pb2+ + 2e–→ Pb     E° = –0.13 V

              Cu2+ + 2e–→ Cu     E° = +0.34 V

If the Pb2+ and Cu2+ are each 1.0 M, the potential of the cell, in volts, is:


◦ 0.47 V
◦ 0.92 V
◦ 0.22 V
◦ 0.58 V
◦ None of these are correct.
