What is ZnSO3? Important knowledge about ZnSO3.

Hello students, today we will learn about ZnSO₃

1. ZnSO₃, also known as Zinc Sulfate(II), in English is Zinc Sulfate. ZnSO₃ is a chemical compound with the formula ZnSO₃. In terms of atoms, we need to note that ZnSO₃ consists of 3 chemical elements: Zinc (Zn), Sulfur (S), and Oxygen (O). Therein, the atomic mass of Zn is 65.38, S is 32.06 and O is 16. Therefore, the molecular weight of ZnSO₃ is 161.44 g/mol.

1.4 Ion structure: ZnSO₃ is a salt of zinc and sulfuric acid. Zinc ion (Zn₂+) forms a compound with sulfate ion (SO₄₂-).

2. ZnSO₃ has distinctive physical and chemical properties:
   2.1 Regarding physical properties: they have a solid state at room temperature, white color, odorless and in crystal form. The pH of a 1M ZnSO₃ solution is about 4.5, indicating that it is slightly acidic.
   2.2 Regarding chemical properties: ZnSO₃ can react with other substances such as metals, acids, non-metals, or salts to form new compounds.

3. Examples of some chemical equations involving ZnSO₃:

Zn + H₂SO₄ -> ZnSO₄ + H₂(Reactionwithacid)
ZnSO₃ + 2NaOH -> Na₂SO₃ + Zn(OH)₂(Reactionwithalkali)
ZnSO₃ + K₂Cr₂O₇ + H₂SO₄ -> ZnSO₄ + Cr₂(SO₄)₃ + K₂SO₄ + H₂O(Redoxreaction)

4. Synthesis of ZnSO₃:
   ZnSO₃ can be synthesized in the laboratory through the reaction between zinc and dilute sulfuric acid. Industrially, ZnSO₃ can also be produced by extracting zinc from sources such as sphalerite.
