the colour of feso4.7h20 is blue green.
On heating iron sulphate first loses its water of crystallization and the original green crystals are converted into a brown coloured anhydrous solid
when further heated the anhydrous material releases sulphur dioxide and white fumes of sulphur trioxide leaving a reddish brown iron(III) oxide
