Question

What will happen if : a) Green vitriol is heated strongly​

Answer 1

$\huge\pink{\boxed{\bold{☞Answer}}}$

Water is losed to form ferrous sulphate.

Answer 2

Answer:

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)
