Zn (zinc) element of forms amphoteric oxide i.e.

Z n O

. This oxide reacts with both acids and bases, exhibiting a dual behaviour. They show characteristics of both acidic as well as basic oxides

Following reaotions are given by

Z n O

Z n O + 2 H Cl \to Z n C l_{2} + H_{2} O

Z n O + 8 N a O H \to N a_{2} Z n O_{2} + H_{2} O

Note 1 Among oxides, OO is neutral,

C a O

is basilo and

S O_{2}

is acidic in nature
