What name is given to those metal oxides which show basic as well as acidic behaviour?
Oxides that show both acidic and basic characters are called amphoteric oxides. E.g. aluminium oxide, zinc oxide
(a) Write one reaction in which aluminium oxide behaves as a basic oxide and another in which it behaves as an acidic oxide. (b) What special name is given to substances like aluminium oxide? (c) Name another metal oxide which behaves like aluminium oxide.
Metal oxides which react with both, acids as well as bases, to produce salt and water are known as ___ oxides.
