Question

Zn metal shows amphoteric behaviour. It can be shown by
(а) its reaction with dil. NaOH only
(b) its reaction with dil. HCl only
(c) its reaction with both dil. HCl and dil. NaOH
(d) it does not react with either dil. HCl or dil. NaOH

​

Answer 1

Explanation:

Amphoteric oxides can behave as an acid as well as base. They react with both acids and bases to form salts. Tin oxide although doesn't ...

Answer 2
