This oxide has the identical density since the metallic aluminium, so it doesn't crack or wrinkle when it can be shaped, a Fortunate matter. Somewhat HCl or NaOH that dissolves the oxide will permit the evolution of hydrogen. Aluminium pots and pans shouldn't be utilised with acidic or strongly alkaline foods, that could dissolve the protective layer and permit the steel being attacked. Aluminium is attacked by hydrochloric acid, although not by oxidizing acids like nitric. Aluminium tank vehicles are even utilised to move nitric acid.
