amphoteric
Reacts with either
Amphoteric describes substances that can act as either an acid or a base depending on their chemical environment.
Water is the classic example—it can donate or accept hydrogen ions.
Amphoteric compounds react with both acids and bases, making them chemically versatile: Aluminum oxide is amphoteric, dissolving in both hydrochloric acid and sodium hydroxide.
