Question

Normally metal oxides are basic.Then why ZnO is amphoteric??pls hlp...​

Answer 1

Answer:

Zno is an amphoteric oxide,because it can react with both acids and bases. while in general most oxides only react with acids alone due to its basic nature. Amphoretic oxides contradicts the Bronsted –Lowrey theory of acids and bases. Al2O3,SnO and ZnO are typical examples for amphoteric oxides

Answer 2

Answer:

ZnO is an amphoteric oxide,because it can react with both acids and bases. while in general most oxides only react with acids alone due to its basic nature.

Explanation:

Amphoteric basically means oxides that can react with both bases and acids.

It will give salt and water in both the reactions.

Amphoteric oxide + acid --> salt + water

Amphoteric oxide + base --> salt + water
