Zinc Nitrate Formula, Properties and Uses

Zinc nitrate has the chemical formula Zn(NO3)2 and is a chemical compound. It is a crystalline solid that is highly soluble in water. Zinc nitrate is formed by the reaction of zinc metal with nitric acid. It is also prepared by dissolving zinc oxide or zinc carbonate in nitric acid.

Zinc Nitrate Properties

Zinc nitrate is an ionic compound consisting of zinc ions (Zn2+) and nitrate ions (NO3-). It is white crystals which are hygroscopic, they can absorb moisture from the air.

Density: 2.065 g/cm³ 

Melting Point: 36.4 °C (97.5 °F) 

Boiling Point: decomposes above 125 °C (257 °F) 

Solubility: Highly soluble in water, and also soluble in ethanol.

Zinc Nitrate Formula, Properties and Uses

Some important properties of zinc nitrate

  1. Solubility: Zinc nitrate is highly soluble in water, and forms a clear solution that dissolves easily in water.
  2. pH: When dissolved in water, the presence of nitrate ions makes the solution acidic, which releases hydrogen ions (H+) into the solution.
  3. Hydration: Zinc nitrate can exist in various hydrated forms, such as the tetrahydrate (Zn(NO3)2 4H2O) and the hexahydrate (Zn(NO3)2 6H2O). These hydrated forms contain water molecules coordinated with zinc and nitrate ions.
  4. Decomposition: When it is heated, zinc nitrate decomposes, releasing nitrogen dioxide gas (NO2), oxygen gas (O2), and leaving behind zinc oxide (ZnO).

Zinc nitrate must be handled with care because it is a hazardous material. It causes irritation to the skin, eyes, and respiratory system, and ingestion or inhalation of large amounts can be toxic. Proper safety precautions, such as wearing gloves and goggles, should be followed when working with zinc nitrate.

Zinc Nitrate is Used in Various Applications

It is used as a precursor for the synthesis of other zinc compounds. 

It is used to make zinc oxide, zinc hydroxide and zinc carbonate etc.

Zinc nitrate is used in the electroplating industry to coat objects with zinc.

It is used as a catalyst in various chemical reactions. For example, it is used as a catalyst in the synthesis of organic compounds and in the oxidation of alcohols.

Zinc nitrate is used in the textile industry for dyeing and printing fabrics.

Zinc nitrate is used as a wood preservative to protect wood from decay and insect damage.

What is zinc lead ii nitrate yield zinc nitrate lead

The reaction between zinc (Zn) and lead (II) nitrate (Pb(NO3)2) yields zinc nitrate (Zn(NO3)2) and lead (Pb).

Zn + Pb(NO3)2 → Pb + Zn(NO3)2

In this reaction, zinc displaces lead from lead(II) nitrate, resulting in elemental lead and zinc nitrate. Zinc is a more reactive metal than lead, so it displaces lead from its compound.

Zinc nitrate is heated balanced equation

The balanced chemical equation for the decomposition of zinc nitrate on heating is as follows

2Zn(NO3)2 → 2ZnO + 4NO2 + O2

This reaction is thermal decomposition, which is a type of chemical reaction that occurs when a zinc nitrate is heated and breaks down into simpler substances. In this case, zinc nitrate breaks down into zinc oxide, nitrogen dioxide, and oxygen gas.

The reaction is exothermic and it releases heat. This heat can be used to generate electricity or to heat other substances.
