why does 10% sulfuric acid not react with
aluminum sheet?10% sulfuric acid has a high concentration and will be passivated and formulate a layer of oxide film after reacting with aluminum,and the reaction will stop after seperating sulfuric acid
and aluminum. there is a layer of Al2O3 oxide film on the surface of aluminum, so it\'s hard for sulfuric acid to break the oxide film and react with aluminum.Other related question
