Question 6. What are amphoteric oxides? Give two examples of amphoteric oxides.
Answer: Oxides of metals which have both acidic as well as basic behaviour are known as amphoteric oxides. Such metallic oxides react with acids as well as base to produce salt and water. Examples of Amphoteric oxides are aluminium oxide and zinc oxide.

Please elaborate it is a wage answer. Better than this I can answer and please give chemical equations.
ReplyDeleteSpelling of vague is wrong
DeleteNo its complete anser
DeleteIs PbO2 a amphoteric oxide
DeleteSpelling of vague are wrong
ReplyDeletehahahahaa
DeleteIt's actually
ReplyDeleteSpelling of Vague IS wrong.
It's actually

ReplyDeleteCan u plzzz elaborate this answer with a chemical equation please ЁЯЩП
ReplyDeleteVague spelling is wrong... Bro
Improve your answer bro
Metal Oxide are usually basic in nature but some metal oxide such as aluminium oxide and zinc oxide react both with acids as well as bases to produce salt and water. Hence they are called as Amphoteric Oxides.
ReplyDeleteChemical equation:-
1) Al2O3 + 6HCL ----- 2ALCL3 + H2O
2) AL2O3 + 2NaOH ----- 2NaAlO2 + H2O
Question___ what do you mean by Amphoteric oxide. Name two metals which form Amphoteric oxide. Justify your answer with chemical equation for any one metal.
Thanks ...it's really helpful
