Synthesis and reactionsEdit
- Zn + 2 HNO3 (diluted) → Zn(NO3)2 + H2
- 4 Zn + 10 HNO3 (concentrated) → 4 Zn(NO3)2 + NH4NO3 + 3 H2O
- 2 Zn(NO3)2 → 2 ZnO + 4 NO2 + O2
Zinc nitrate has no large scale application but is used on a laboratory scale for the synthesis of coordination polymers. Its controlled decomposition to zinc oxide has also been used for the generation of various ZnO based structures, including nanowires.
