What are amphoteric oxides? Give two examples of amphoteric oxides.
Amphoteric oxides frm salt nd watr aftrr reatng wth acd nd base both.....
Fr E.g NAOH nd ZnO
Amphoteric oxides react with both, acid as well as bases to form salt and water.
Aluminium oxide react with HCL acid to form aluminium chloride(salt) and water. In this reaction aluminium oxide react with acid and behaves as basic oxide. Also aluminium oxide reacts with NAOH to form sodium aluminate(salt) and water. In this reaction aluminium oxide react with base and form salt and water.
