The 'oxide and water' approach allows the focus to remain on the main teaching point without the need to cover another set of reactions (although these could be covered with an appropriate group of students). In general, metal oxides are basic and non-metal oxides are acidic. Some metal oxides react with water to form alkaline solutions.

The word has Greek origins, amphoteroi (άμφότεροι) meaning "both". Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation state of the oxide. For example, zinc oxide (ZnO) reacts with both acids and with bases: In acid: ZnO + 2H + → Zn 2+ + H 2 O.
