the corrosion potential and corrosion rate of an iron pipe carrying 1 Nsulfuric acid at 0.2 m/s at 25 ° C. Assume that the entire iron surface acts ascathode, that Tafel slopes are ± 0.100 V, and that the exchange current densities forFe/Fe 2+ and for hydrogen on iron are 10-3 and 10-2 A/m 2, respectively.
