Solution
Acidic oxide: Non-metallic oxides are acidic oxides.
\[\ce{SO2, CO2, NO2}\] is an acidic oxide.
Basic oxide: Metallic oxides are basic oxides.
\[\ce{Na2O, K2O}\] is a basic oxide.
Amphoteric oxide: Oxides of metals like Zn, Pb, Al are amphoteric oxides.
\[\ce{Al2O3}\] is an amphoteric oxide.
Neutral oxide: Oxides like \[\ce{NO, CO, N2O}\] are neutral oxides.
Amphoteric oxide reacts with acids and bases to give salt and water.
