Zinc nitrate - Zn(NO3)2

What is Zinc nitrate?

Zn(NO3)2 is an inorganic chemical compound with a chemical name Zinc nitrate. It is also called Zinc dinitrate or Celloxan or Zinc Nitrate Hexahydrate. It is widely used as a catalyst to manufacture in medicine, dyes, and various other chemicals.

Celloxan is a white to colourless, crystalline solid which is highly deliquescent. It is soluble in alcohol as well as water. It is a non-combustible compound but has the power to accelerate burning of other combustible compounds. Toxic oxides of nitrogen are liberated when heated.

Zn(NO3)2 Uses (Zinc nitrate)

  • Zinc nitrate is used as synthesis of coordination polymers.
  • Used in dyeing as a mordant.
  • Used as a catalyst in resin production.
  • Used as a strong oxidizing agent.
  • Used in liquid fertilizers.
  • Used as a latex coagulant.
  • Used in the manufacturing of medicines.

Production of Zinc nitrate

It is produced by dissolving zinc in nitric acid. The reaction is concentration dependent, and forms ammonium nitrate. The reaction is given below:

Zn + 2 HNO3 (diluted) → Zn(NO3)2 + H2

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

It undergoes thermal decomposition on heating and forms zinc oxide, oxygen, and nitrogen dioxide.

2 Zn(NO3)2 → 2 ZnO + 4 NO2 + O2

Health hazards

Inhaling dust causes irritation in the throat and nose. Swallowing Zinc dinitrate can lead to corrosion of the alimentary tract. Contact with skin results in irritation and can cause rashes.

When heated it may liberate toxic oxides of nitrogen. When it comes in contact with combustible material it can increase the fire intensity.

Frequently Asked Questions

What is zinc nitrate used for?

Zinc nitrate does not have a broad scale use, but is used for the synthesis of coordinating polymers on a laboratory scale. The controlled decomposition to zinc oxide can also be used for the generation of various structures, including nanowires. It can also be used as a dyeing mordant.

Is zinc nitrate acidic or basic?

Hydroxide anions coming from water can liberate the nitrate anions when zinc nitrate is put in an aqueous solution. HNO3 doesn’t look like a molecule, mind you! The reaction results in the formation of hydronium ions , which is why the solution can be considered acidic.

Does nitric acid react with zinc?

Aluminum and zinc do not react with concentrated nitric acid due to the formation of a dense, hard to dissolve oxidation layer due to a process known as passive oxidation. This protects the metal against further reaction and corrosion. Nevertheless, zinc does react with dilute nitric acid.
