Solution :
Although ZnO is an amphoteric oxide but in given reaction. [a] \[\underset{\text{acid}}{\mathop{ZnO}}\,+\underset{\text{base}}{\mathop{N{{a}_{2}}O}}\,\xrightarrow{{}}\underset{\text{salt}}{\mathop{N{{a}_{2}}Zn{{O}_{2}}}}\,\] [b] \[\underset{\text{base}}{\mathop{ZnO}}\,+\underset{\text{acid}}{\mathop{C{{O}_{2}}}}\,\xrightarrow{{}}\underset{\text{salt}}{\mathop{ZnC{{O}_{3}}}}\,\]You need to login to perform this action.
