Oxides of Metals are:
Acidic
Basic
Amphoteric oxides
Both basic and amphoteric oxides.
Metal oxides are basic in nature but some metal oxides, such as aluminium oxide and zinc oxide show amphoteric behaviour.
(a) What are amphoteric oxides? Give two examples of amphoteric oxides. (b) Choose the acidic oxides, basic oxides and neutral oxides from the following: Na2O:CO2;CO;SO2;MgO;N2O;H2O. (c) Which of the following are amphoteric oxides: MgO,ZnO,P2O3,Al2O3,NO2
