The color of the heptahydrate FeSO4. 7 H2O is green.
After thermal dehydration the monohydrate FeSO4.H2O is formed and this is colorless.
The color of crystals will change after heating because of loss of water..
The color of ferrous sulphate crystals is green. However on heating, it yields a brownish mass ( as water is lost) and on further heating they lead to release of a mixture of sulfur dioxide and sulfur trioxide
Ferrous Sulphate, also known as Iron (II) sulphate or green vitrol is green.
Ferrous sulfate is green in color
faded green in colour

ferrous sulphate when it is heated it changes into red brown color
Ferrous Sulphate, also known as Iron (II) sulphate or green vitrol is green.
Ferrous sulfate is green in color
faded green in colour
It is pale green in colour.
brown colour
The aqueous solution of ferrous sulfate, FeSO4, is light green on heating. It changes to yellow then brown due to formation of ferric sulfate.
This is because sulphate is a thing that just dissolve in the water and changes the colour.
brickish color
Iron oxide is red. The presence of iron oxide on the surface of Mars gives the planet its color and nickname "The Red Planet."
