What is CrSO4? Important knowledge about CrSO4.

1. Definition of CrSO₄

CrSO₄, commonly known as Sulphate Chrom or Chromium(II) sulfate in English, is a chemical compound. The structure of CrSO₄ consists of a Chromium (Cr) atom, a Sulfur (S) atom, and 4 Oxygen (O) atoms. Its atomic mass is about 152.00 g/mol. In terms of ionic structure, CrSO₄ disassociates in water to form Cr₂+ ions and SO₄₂- ions.

2. Characteristics of CrSO₄:

2.1 Physical properties of CrSO₄:
The state of CrSO₄ under standard conditions is crystalline solid, its color is usually blue or green and it is odorless. The PH value of CrSO₄ solution in water is usually acidic.

2.2 Chemical properties of CrSO₄:
CrSO₄ is capable of reacting with various other substances such as acids, bases, metals, and non-metals to form new compounds.

3. Common chemical equations of CrSO₄:

• Reaction with acid: CrSO₄ + H₂SO₄ -> Cr(SO₄)₂ + H₂
• Reaction with metals: CrSO₄ + Ba -> BaSO₄ + Cr
• Reaction with non-metals: CrSO₄ + N₂ -> CrN + SO₄
• Reaction with salts: CrSO₄ + NaCl -> CrCl + NaSO₄

4. Synthesis of CrSO₄:

4.1 Laboratory synthesis of CrSO₄:

• From Cr(OH)₂ and H₂SO₄: Cr(OH)₂ + H₂SO₄ -> CrSO₄ + H₂O
• From CrO and H₂SO₄: CrO₃ + H₂SO₄ -> CrSO₄ + H₂O₂

4.2 Industrial synthesis of CrSO₄:
In industry, CrSO₄ is usually synthesized from chromium ore or from the recycling process of products containing Chromium.
