What is ZnNO3? Important knowledge about ZnNO3.

1. Definition of ZnNO₃

ZnNO₃, also known as Zinc Nitrate, is a chemical substance with the chemical formula Zn(NO₃)₂. In English, its name is Zinc nitrate. It consists of one zinc atom (Zn), two nitrogen atoms (N), and six oxygen atoms (O). The atomic mass of ZnNO₃ is 189.3894, in which zinc accounts for 65.38, nitrogen accounts for 28.01 and oxygen accounts for 95.99. The molecular structure of ZnNO₃ includes one zinc ion (Zn₂+) and two nitrate ions (NO₃-).

2. Properties of ZnNO₃

2.1. Physical properties: ZnNO₃ exists as a solid, colorless and odorless substance. Its pH is in the neutral range.

2.2. Chemical properties: ZnNO₃ can react with some other chemical compounds such as acids, metals, non-metals and salts.

3. Common chemical equations:

Examples of ZnNO₃ reactions:

• With acid: ZnNO₃ + H₂SO₄ -> ZnSO₄ + HNO₃
• With metal: ZnNO₃ + Fe -> Fe(NO₃)₂ + Zn
• With non-metal: ZnNO₃ + P -> Zn₃P₂ + N₂O
• With salt: ZnNO₃ + NaCl -> ZnCl₂ + NaNO₃

4. Preparation of ZnNO₃:

4.1. Lab preparation: ZnNO₃ can be prepared by reacting zinc with nitric acid.

• Zn + 2HNO₃ -> Zn(NO₃)₂ + H₂↑

4.2. Industrial preparation: In industry, ZnNO₃ is usually produced by releasing nitrate from zinc ore.
