Question

FeSO4.7H2O green colour crystals on heating change color.why?

Answer 1

Thank you for the question!
FeSO4.7H2O is blue green color.the anhydrous form of FeSO4 is colorless which mean it has no water in the crystal.The green color of the aqueous solution of FeSo4  is because of the water molecules present in  solution.Moreover,this is also a decomposition process. Thus due to this reason the color of the crystal changes.
Hope it helps.
