Zinc nitrate is an inorganic chemical compound with the formula Zn(NO3)2 . This white, crystalline solid is highly deliquescent and is typically encountered as a hexahydrate Zn(NO3)2•6H2O. It is soluble in both water and alcohol.
Synthesis and reactions[edit]
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
Applications[edit]
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:
