amfoteriset
Amfoteriset, or amphoteric substances, are chemical species that can act both as acids and as bases depending on the reaction partner and the conditions. In practice this means they can donate a proton to a stronger base or accept a proton from a stronger acid. This dual behavior is common among many metal oxides and hydroxides in inorganic chemistry.
Typical examples include water (H2O), aluminum oxide (Al2O3) and zinc oxide (ZnO), as well as hydroxides such
Amphoteric substances show pH-dependent solubility and reactivity. For example, Al2O3 dissolves in acidic solutions to form
Applications of amphoteric materials include catalysis, corrosion science, soil and environmental chemistry, and materials science. Understanding
