WebMar 31, 2024 · Amphoteric Hydroxides act either as Bronsted-Lowry bases (accepting protons) or as Lewis acids (accepting an electron pair), depending on reaction conditions. For example, $\ce{Al^3+}$ in $\ce{Al(OH)3}$ is a Lewis acid, which can accept an electron pair from either Lewis or Bronsted-Lowry base: Metal oxides which react with both acids as well as bases to produce salts and water are known as amphoteric oxides. Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Aluminium oxide (Al 2 O 3) is an example of an amphoteric oxide.
