Question
Give the example of the acidic oxide, basic oxide, amphoteric oxide and neutral oxide. State which of the oxide react with acids and bases to give salt and water.
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.
