Question

One molecule of hydrated ${\mathrm{CuSO}}_4$ contains how many molecules of water of crystallization?

Answer 1

Hydrated ${\mathrm{CuSO}}_4$:

• The chemical formula of hydrated Copper sulphate is ${\mathrm{CuSO}}_4.5{\mathrm{H}}_2\mathrm{O}$.
• It contains five molecules of water of crystallization and appears as blue-colored crystals.
• On heating changes from blue to white and the crystalline form changes to amorphous.

Therefore, one molecule of hydrated ${\mathrm{CuSO}}_4$ contains five molecules of water.
