For the above current at 5.21 V, how much electrical energy
(in kw-hr) is consumed in the production of 1 kg of aluminum? (The
electrical energy or work =qV and 1 kW-hr is 3.6 x106 J.)
b)
Calculate the potential of the Pb/Pb(IO3)2 electrode in a
0.00057 M solution of NaIO3.
c)
Air is 21 mole percent oxygen, that is, 0.21 atm oxygen at 1
atm. Suppose the pH of the water is 5.28 and that the concentration
of iron(II) in the water is 5.38x 10-5 M, what is the potential of
the corrosion reaction under the above conditions at 298 K?
