How is the equation for CuSO₄ + H₂O determined?

Answer:

H₂O + CuSO₄ → 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.
