QUESTION :-
What are amphoteric oxides?
ANSWER:-
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.
ZnO + 2NaOH → Na2ZnO2 + H2O.
OR
Amphoteric oxides: Those oxides that behave as both acidic and basic or that can react with acid as well as base are called amphoteric oxides. Example: aluminium oxide Al2O3, zinc oxide ZnO. Acidic nature: ZnO reacts with hydrochloric acid forming zinc chloride and water. ... ZnO + 2NaOH → Na2ZnO2 + H2O.
QUESTION:-
Choose the amphoteric oxides from amongst the following oxides:
Na2O , Al2O3 , ZnO , CO2 , K2O .
Answer:-
ZnO & Al203 is amphoteric oxides
EXPLANATION:-
Na2O, ZnO, Al2O3 CO2, H2O. (a) Metal oxides that react with both acids and bases to produce salt and water are known as Amphoteric oxides. For example, zinc reacts with an acid or a base to produce salt and water. Amongst the given oxides, zinc oxide (ZnO) and aluminium oxide (Al2O3) are amphoteric oxides
