Fundamental Studies on Corrosion of Copper by Sulfuric Acid in the Atmosphere (III)

Abstract

The effect of cupric ion on the corrosion of copper in a dilute sulfuric acid solution was studied by using polarization conductance.
The square root of the concentration of cupric ion was found to be proportional to the corrosion rate.
The corrosion rate also increased with pH, when the solution included cupric ion.
These results were successfully explained with the reaction mechanism having proposed by the authors in the previous papers.
It was estimated that the increase in corrosion rate with time would continue as long as the active dissolution proceeded.
