Aluminum reacts differently with acids and bases. With acids, aluminum undergoes a redox reaction where it loses electrons and forms Al^3+ ions. This reaction is exothermic and releases hydrogen gas. The general reaction with a non-oxidizing acid like hydrochloric acid is: 2Al + 6HCl 鈫?2AlCl鈧?+ 3H鈧? In the presence of a strong base, aluminum reacts with water to form aluminate ions and hydrogen gas, a process known as an alkaline hydrolysis. The reaction can be represented as: 2Al + 2OH鈦?+ 6H鈧侽 鈫?2Al(OH)鈧勨伝 + 3H鈧?
