Question

How does the colour change in ferrous sulphate crystals?

Answer 1

Explanation:

The color of ferrous sulphate crystals is green. Ferrous sulphate crystals contain water molecules (FeSO4. ... 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).

Answer 2

Explanation:

on heating ferrous sulphate crystal loss water and anhydrous ferrous sulphate is formed. so their colour change from light green to White. on further heating anhydrous ferrous sulphate decomposes to form Ferric oxide, sulphur dioxide and sulphur trioxide
