Question

what is the colour of FeSO4 . 7 H2O crystal? How does this colour change up on heating? Give the balanced chemical equation​

Answer 1

Answer:

The colour of FeSO4.7H2O is green (green vitriol). On heating,it loses its water of crystallization and changes to white colour.

FeSO4.7H20 + ∆ ---------> FeSO4 + 7H20

Answer 2

Answer: blue green is the colour of FeSO4 . 7 H2O crystal.7H2O). On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white. On further heating, anhydrous ferrous sulphate decomposes to form ferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur trioxide (SO3).
