How is the equation for CuSO4 + H2O determined?


H2O + CuSO→ CuSO4.5H2O

The reaction between H2O and CuSO4 gives CuSO4.5H2O which is blue vitriol. The end product is known as copper sulfate pentahydrate. On dehydration of copper sulfate, the water molecule is lost resulting in the formation of copper sulfate monohydrate which is bluish-white colour.

CuSO4 + 5H2O →CuSO4.5H2O

Application of blue vitriol

Applications of blue vitriol:

  • Used as a herbicide and a fungicide.
  • It is used as an analytical reagent.
  • It is used as battery electrolytes.
  • Used as a mordant during a vegetable dyeing process.
