WebAmphoteric oxides are a curious group of oxides that can behave as both acidic and basic, depending on whether the other reactant is an acid or a base. In both cases salt and water are formed. Two of the most common amphoteric oxides are zinc oxide, ZnO and aluminum oxide, Al2O3. The hydroxides of both of these elements also behave amphoterically. WebJan 12, 2024 · Amphoteric Surfactants. Amphoteric surfactants have a dual charge on their hydrophilic end, both positive and negative. The dual charges cancel each other out creating a net charge of zero, referred to as zwitterionic.
