Zinc nitrate is a salt of zinc with the formula Zn(NO3)2. Zinc nitrate is highly deliquescent and is typically encountered as a hexahydrate, Zn(NO3)2·6H2O, though a trihydrate is also known.
- Zn(NO3)2 → ZnO + 2 NO2 + ½ O2
Zinc nitrate is an odorless hygroscopic solid, soluble in water and alcohols.
Zinc nitrate is available as Zn+N fertilizer, though not always as pure substance.
Zinc nitrate is sold by chemical suppliers, most of the time as hexahydrate. It can also be purchased on eBay and Amazon.
- ZnO + 2 HNO3 → Zn(NO3)2 + H2
- Zn(OH)2 + 2 HNO3 → Zn(NO3)2 + 3 H2
- ZnCO3 + 2 HNO3 → Zn(NO3)2 + H2 + CO2
If zinc metal is used, diluted nitric acid should be used, as reaction of zinc metal with concentrated nitric acid also produces ammonium nitrate.
- Zn + 2 HNO3 (dil.) → Zn(NO3)2 + H2
- 4 Zn + 10 HNO3 (conc.) → 4 Zn(NO3)2 + NH4NO3 + 3 H2O
- Make flash powders
- Make nitrogen dioxide and nitric acid
- Compound collecting
Zinc nitrate is irritant and a strong oxidizer, though it's hygroscopicity limits its oxidizing power.
Should be stored in closed, air-tight containers, away from flammable materials.
Addition of a soluble carbonate will precipitate zinc carbonate.
Unless contaminated with heavy metals, diluted solutions of zinc nitrate can be used as fertilizer.
