What is the chemical reaction between aluminum and acid?

When aluminum reacts with an acid, it undergoes a single displacement reaction. The general reaction can be represented as: 2Al + 6HCl 鈫?2AlCl鈧?+ 3H鈧? In this reaction, aluminum (Al) displaces hydrogen (H) from the hydrochloric acid (HCl), forming aluminum chloride (AlCl鈧? and hydrogen gas (H鈧?. The aluminum atoms lose three electrons each to form Al鲁鈦?ions, while the hydrogen ions (H鈦? from the acid gain electrons to form hydrogen gas. This reaction is exothermic, releasing heat and often producing bubbles of hydrogen gas.
