Question

Why is ZNO called an amphotaric oxide? Give reactions also​

Answer 1

Answer:

ZnO is called as an amphoteric oxide as because it act as both acidic and basic.

It also forms water and salt

Explanation:

ZnO+H2SO4=ZnSO4+H2O

ZnO+2NaOH=Na2ZnO2+H2O

Answer 2

Explanation:

ZnO is called as an amphoteric oxide because it reacts with both acids and bases to give same products i.e., salt and water.

$\mathfrak{\pink{Reaction\:of\:zinc\:oxide\:with\:Hydrochloric\:acid:}}$

$ZnO + 2HCl ------> ZnCl_2 + H_2O$

$\mathfrak{\purple{Reaction\:of\:zinc\:oxide\:with\:Sodium\:hydroxide:}}$

$ZnO + 2NaOH ------> Na_2ZnO_2 + H_2O$

$\mathsf{\huge{\boxed{\pink{Amphoteric\:oxides:}}}}$

The oxides which reacts with both acids as well as base to give same products i.e., salt and water are called as Amphoteric oxides. Eg: Zinc oxide and Aluminium oxide.
