3-10. Plot the polarization data shown below for an electrode of 1.13 cm of the metal M in an acid solution of unit activity bubbled with pure hydrogen. How might the potentials in this data have been measured experimentally? From your plot, determine the corrosion rate (current density) and the exchange current density for the hydrogen reduction reaction on the surface of M. Comment on the accuracy of your determinations.
