Abstract

Steady state current-potential curves for the anodic dissolution of zinc in aqueous-methanolic 0.25M trichloracetic acid solutions were constructed for wide ranges of the solution composition and temperature. Analysis of the results reveal that the increase of the water content and rise of temperature of the solution increases the corrosion rate. The most plausible role of the solvent lies within the stabilization of the anodic dissolution reaction products by water molecules. The changes in the properties of the solution due to the presence of methanol which give rise to hindrance of the anodic dissolution reaction are adsorption of methanol, change of viscosity and pH of the solution. These factors seem to be of secondary importance.
