Celloxan is a white to lớn colourless, crystalline solid which is highly deliquescent. It exists as hexahydrate i.e, Zn(NO3)2•6H2O. It is soluble in alcohol as well as water. It is a non-combustible compound but has the power to accelerate the burning of other combustible compounds. Toxic oxides of nitrogen are liberated when heated.

Zn(NO3)2 Uses (Zinc nitrate)

Zinc nitrate is used in the 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, và 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 và forms zinc oxide, oxygen, & nitrogen dioxide.

2 Zn(NO3)2 → 2 ZnO + 4 NO2 + O2

Health hazards

Inhaling zinc nitrate dust causes irritation in the throat and nose. Swallowing Zinc dinitrate can lead khổng lồ corrosion of the alimentary tract. Tương tác with the skin results in irritation & can cause rashes.

When heated, it may liberate toxic oxides of nitrogen. When it comes in tương tác 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 khổng lồ 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?

Zinc nitrate is a salt of a weak base & strong acid. Zinc nitrate ionises khổng lồ give zinc and nitrate ions in water. The basic radical Zn2+ hydrolysis to lớn give weak base Zn(OH)2 & H+ ions are released which makes the solution acidic.

Does nitric acid react with zinc?

Aluminium và zinc vì chưng not react with concentrated nitric acid due to lớn the formation of a dense, hard-to-dissolve oxidation layer due to lớn a process known as passive oxidation. This protects the metal against further reaction và corrosion. Nevertheless, zinc does react with dilute nitric acid.
