Question

What happens if you put copper sulfate crystals in water?

Answer 1

Copper sulfate:

• The chemical formula for coper sulfate is ${\mathrm{CuSO}}_4$.
• It is also known as blue vitriol.

Copper sulfate is categorized into two forms:

• Anhydrous copper sulfate
• Hydrated copper sulfate

Anhydrous copper sulfate:

• It is white in color having chemical formula ${\mathrm{CuSO}}_4$.
• It does not contain water in it.

Hydrated copper sulfate:

• When water is added to the anhydrous copper sulfate solution, then it turns into a hydrated form of copper sulfate.
• Commonly used hydrated form of copper sulfate is ${\mathrm{CuSO}}_4.5{\mathrm{H}}_2\mathrm{O}$.
• It is bright blue in color due to the d-d transitions that take place between the ligands and the central metal atom.
