Abstract
A study has been made of the reactivity of pure aluminum with cerium+4 sulfate in sulfuric acid. Electrode potentials, weight loss data, and polarization curves are presented, and it is shown that the reaction may be interpreted from an electrochemical point of view. The theory of the “mixed potential” is suggested as a more generalized concept than the local cell idea for the interpretation of the dissolution process. A brief outline of a probable mechanism for the dissolution and passive behavior of aluminum is presented.
