Aluminum can be oxidized by acid. It readily reacts with many acids
Can aluminum be oxidized by acid?
Acid has the ability to oxidize aluminum. Because of its active nature (willingness to lose electrons and become a positive ion) and the presence of protons in acids (proton donors), it reacts readily with a wide range of acids, including hydrochloric, sulfuric, and nitric. The acid used determines the particular reaction and products.
Aluminum, for instance, reacts with hydrochloric acid to form aluminum chloride and hydrogen gas. Strong acids have the ability to dissolve the protective oxide layer that covers aluminum, allowing for additional oxidation.
