How to know the list of amphoteric oxides


As Amphoteric (from ancient Greek ἀμφοτέρως, amphoteros In chemistry, one describes a substance that - depending on the milieu or reaction partner - reacts in one way or the other.

  • Acid-base amphoters are also known as ampholytes. These can react both as acids and as bases.[1] Amphoteric substances thus react to stronger bases such as acids and to stronger acids such as bases. The amphoterics include various metal oxides and metal hydroxides (see table) and the amino acids.[2]
  • Redox amphoters are substances that can have both an oxidizing and a reducing effect. Example: hydrogen peroxide
  • Amphoteric surfactants have a cationic and an anionic part and are important as surface-active substances.[1]

Amphoteric hydroxides are those hydroxide compounds that are soluble in both acidic and alkaline media:

A second meaning of amphoteric occurs in solid state physics. In doping, dopants that can act as acceptors and donors are called amphoteric.
