Question

Identify gas that turns anhydrous copper sulphate blue crystalline

Answer 1

the answer is water gas

Answer 2

Water turns anhydrous copper sulphate into blue crystalline.

• Pure copper (II) sulfate is white compound.  

• It is also known as anhydrous copper (II) sulfate as it has no water in it.  

• When water exist in a sample of copper (II) sulfate it goes blue.  

• When it turns blue then It is still a dry solid, since the discrete water molecules are stuck within the ionic lattice surrounding the copper (II) ions.
