Question

Zinc oxide is an amphoteric oxide. Justify your answer with equations.

Answer 1

Hey mate!!!

➡️Zinc oxide is amphoteric in nature it means it react with acid as well as base.

eg-- Zn + HCl -> ZnCl2 + H2O ( acid)

Zn + NaOH -> Na2ZnO + H2O ( Alkaline salt).

➡️From above eg. we say that ZnO is amphoteric in nature.

Answer 2

Answer:

Amphoteric oxides are the ones that can react with both acid and bases to form salts.

Explanation:

ZnO is an example of amphoteric oxide as it can also react with both the acids and bases. For example:

Reaction of zinc oxide with an acid:

ZnO + H2SO4 ------ ZnSO4 + H2O

Reaction of zinc oxide with a base:

ZnO + 2NaOH ----- Na2ZnO2 + H2O

Hence, it can react with both H2SO4 and NaOH. Therefore, it's an example of amphoteric oxides.
