(From Wikipedia, the free Encyclopedia)
Amphoteric describes something made of two components, or acting like two different components.
In chemistry, it means a substance that can act as either acid or base. An example is amino acids and water. Similar many metals, such as zinc, tin, aluminium or beryllium. E.g. Zinc-oxide ZnO reacts differently depending on the pH of the solution:
In acids:ZnO + 2H+ --> Zn2+ + H2O
In bases:ZnO + H2O + 2OH- --> [Zn(OH)4]2-
This effect can be used to separate different kations, such as zinc from manganese.
