A Metal That Forms An Oxide Of Formula R2o3

 · In general, if the volume of the metal oxide per mole of metal is greater than the molar volume of the metal, the oxide will form a protective scale. On the other hand, if the oxide formed occupies a smaller volume than the volume occupied by the metal itself, the oxide layer will be under tension and at some point it will crack.

Cells are set up in the metal surface where different areas act as sites of oxidation and reduction The two half cells are F e2 aq 2e F e s E0 1 44V 1 2 O2 g H 2O l 2e 2OH aq E0 0 40V The most positive half cell is the one which will take in electrons so you can see that O2 H 2O will oxidise F e to F e2
