standard potential values on this new scale differ from
those in Appendix 6?

phenomenon known as waterline corrosion. Assuming the
oxidizing agent in the corrosion process is O2, propose a
reason why metal pilings such as this one tend to corrode
the most at the waterline and corrode less at heights above
and below the waterline.
