Synthesis and reactionsEdit

Zinc nitrate is usually prepared by dissolving zinc in nitric acid, this reaction is concentration dependent, with a reaction in concentrated acid also forming ammonium nitrate:

Zn + 2 HNO3 (diluted) → Zn(NO3)2 + H2
4 Zn + 10 HNO3 (concentrated) → 4 Zn(NO3)2 + NH4NO3 + 3 H2O

On heating, it undergoes thermal decomposition to form zinc oxide, nitrogen dioxide and oxygen.

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.[1] Its controlled decomposition to zinc oxide has also been used for the generation of various ZnO based structures, including nanowires.[2]

It can be used as a mordant in dyeing. An example reaction gives a precipitate of zinc carbonate:

Zn(NO3)2 + Na2CO3 → ZnCO3 + 2 NaNO3
