Question

identify me I am blue in colour have a drop of water in my body and turn it into white powder when heated to I am what is my molecular formula​

Answer 1

Answer:

AS color of copper is sulphate is blue and it has a drop of water (H₂O) and when we will heat it then a white powder will formed.

Answer 2

Answer:

Copper sulphate crystals with formula- CuSO₄.5H₂O

Explanation:

• A solution of copper sulphate (CuSO₄.5H₂O) in water is blue due to the d-d transition of ligands (H₂O) around it.

• In CuSO₄.5H₂O, this H₂O refers to the water of crystallization.

So as per the question,

• Upon heating, the water in it gets evaporated and becomes anhydrous.

$CuSO_{4} .5H_{2}O$    →→→   $CuSO_{4} +5H_{2} O_{}$ ↑

(blue)        on heating     (white)

• Salts on heating lose water i.e -after evaporation, change from hydrous to anhydrous salt.

• Thus blue coloured,  hydrous copper sulphate salt upon heating changes and gives white-coloured anhydrous copper sulphate salt.

Hence it is identified as Copper sulphate crystals with the formula- CuSO₄.5H₂O
