Zinc Nitrate Formula: Definition, Structure, Properties and Uses

Zinc Nitrate Formula: Zinc, denoted by the chemical symbol Zn and possessing an atomic number of 30, is not typically found in its elemental state but rather in the form of minerals combined with other chemical elements. This essential trace element is abundant within the human body, primarily concentrated in red blood cells. Zinc is widely utilized in various industries, notably for its role in galvanizing other metals to shield them from corrosion. Additionally, zinc is employed in the production of roofing materials and the creation of zinc oxide.

Nitrogen, symbolized as N with an atomic number of 7 and an electron configuration of 1s ² 2s ² 2p ³ , is the seventh element on the periodic table. A fundamental component of amino acids, nitrogen is a ubiquitous substance on Earth. It ranks as the fourth most prevalent element in living biomass, following hydrogen, carbon, and oxygen. Nitrogen finds diverse applications, including the production of fertilizers, nitric acid, nylon, dyes, and explosives

Zinc Nitrate, represented by the chemical formula Zn(NO ₃ ) ₂ , is an inorganic compound that exists as a colorless crystalline solid. It serves as a catalyst in resin manufacturing, chemical production, and pharmaceuticals. Laboratories employ it for synthesizing coordination polymers. Nitrate compounds generally exhibit high solubility in water and are typically formed by dissolving zinc in nitric acid:

Zn + 2HNO ₃ → Zn(NO ₃ ) ₂ + H ₂

Upon heating, zinc nitrate experiences thermal decomposition, yielding zinc oxide and oxygen:

2Zn(NO ₃ ) ₂ → 2 ZnO + 4 NO ₂ + O ₂

Zinc Nitrate Structure

The chemical formula for Zinc Nitrate is Zn(NO 3 ) 2 . In this arrangement, each nitrogen atom is bonded to three oxygen atoms, satisfying the octet rule. The composition consists of two nitrogen atoms, six oxygen atoms, and one zinc atom. The structural depiction of Zinc Nitrate is provided below.

Zinc Nitrate Preparation

Zinc Nitrate is obtained by dissolving zinc in a nitric acid solution:

With Diluted Nitric Acid:

Zn + 2 HNO ₃ (Diluted) → Zn(NO ₃ ) ₂ + H ₂

With Concentrated Nitric Acid:

4Zn + 10 HNO ₃ (Concentrated) → 4Zn(NO ₃ ) ₂ + NH ₄ NO ₃ + 3H ₂ O

Upon heating, it undergoes thermal decomposition, yielding Zinc oxide, oxygen, and nitrogen dioxide:

2 Zn(NO ₃ )2 → 2ZnO + 4NO ₂ + O ₂
