Generate an Evans diagram for the corrosion of elemental
manganese in oxygen-free 0.5 M H2SO4. From this diagram determine
the corrosion potential and corrosion current. Use this to predict
the corrosion rate of manganese metal. Important relevant
information may include (a) For hydrogen evolution on manganese, E0
= 0.0 V vs SHE, i0 = 0.01 A.m-2 and αc = 0.55; and (b) For
manganese oxidation to Mn2+, E0 = -1.18 V, log(i0) = -4.7 and αa =
0.5.
