Chemical Properties:
As an amphoteric oxide, reacting with acid, alkali, ammonia water produce salt, zincate, complex separately:
ZnO+4NH4OH—Zn(NH3)4(OH)2+3H2O
Reacting to salt produce double salt:
3ZnO+ZnSO4+2H2O-ZnO)3. ZnSO4. 2H2O
Reacting to carbon dioxide in air produce zinc carbonate:
ZnO+CO2—ZnCO3
Zinc oxide could be reduced to metallic zinc by carbon or carbon monoxide, but hydrogen being use as a reducant no metallic zinc could be generated:
ZnO+C—Zn+CO
ZnO+CO—Zn+CO2 |
