Question

Water turns anhydrous copper sulfate blue

• A. True
• B. False

Answer 1

The correct option is A True

• Copper sulfate is a standard sulfate that is white in anhydrous form and blue crystal in hydrated form is commonly involves eliminating algae and fungicide.
• The number of water molecules present in a crystal is called water of crystallization.
• In hydrated copper sulfate, there are five water molecules.

Heating of hydrated copper sulfate.

Due to heating, hydrated blue-coloured copper sulfate$({\mathrm{CuSO}}_4.5{\mathrm{H}}_2\mathrm{O})$ loses water and turns into anhydrous white-coloured copper sulfate (${\mathrm{CuSO}}_4$).

Thus Water turning anhydrous copper sulfate blue is a true statement.
