Abstract

The dissolution rate of aluminum hydroxide in sulfuric and hydrochloric acids was studied as a function of acid concentration, solution temperature, and the hydroxide/electrolyte interfacial potential. It was found to be limited by the transfer of surface complexes from the solid phase to the solution.
