Decomposition of Copper Sulfate Pentahydrate (Tutorial) by TGA-MS and TGA-FTIR

Introduction

The thermal decomposition of copper sulfate pentahydrate (CuSO₄.5H₂O) is used to demonstrate the advantage of an online coupling technique.  CuSO₄.5H₂0 loses its water of crystallization in several steps. The resulting anhydrous copper sulfate decomposes in three further reaction steps as given by the following equations:

(1) 2 CuSO₄ –→ Cu₂(SO₄)O + SO₃

(2) Cu₂(SO₄)O → – 2 CuO + SO₃

(3) 2 Cu0 → – Cu₂0 + ½ 0₂

Sample:                  Copper sulfate pentahydrate  (CuSO₄·5 H₂O)

Measuring cells:    TGA-MS and TGA-FTIR
