Step 1
The first step is to understand the concept of sacrificial protection. In this method, a more reactive metal is used to protect a less reactive metal from corrosion. The more reactive metal corrodes instead of the less reactive metal, thus protecting it. Show more…

For each of the metals listed in the table, compute the Pilling-Bedworth ratio. Also, on the basis of this value, specify whether or not you would expect the oxide scale that forms on the surface to be protective, and then justify your decision. Density data for both the metal and its oxide are also tabulated.
Use $E^{\circ}$ values to predict which of the following metals, if coated on iron, will provide cathodic protection against corrosion to iron. (a) Cu (b) $\mathrm{Mg}$ (c) Ni (d) Sn
Use $E^{\circ}$ values to predict which of the following metals, if coated on nickel, will provide cathodic protection against corrosion to nickel. (a) Cu (b) $\mathrm{Mg}$ (c) Zn (d) $\mathrm{Cr}$
