2. The anodic polarization curve of an active-passive alloy obtained in a chloride containing solution is shown in Figure 1. The quantitative information of the electrochemical parameters is given in the table below. Under applied conditions, the pitting initiation occurs at 0.045V vs. SHE. Assume that the anodic polarization curve is NOT pH dependent. Using the data given in the Table, (a) Determine the pH range at which alloy will become passive assuming the cathodic reaction is hydrogen evolution having following kinetics parameter values [4pts]: ic0=4105[H+];c=0.06 (b) Estimate the pH at the critical pitting potential of 0.045V at which the alloy cannot be passivated [2pts]
