What happens when ferrous sulphate is treated with water?
Ferrous sulphate crystals contain water molecules (FeSO4. 7H2O). On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white.
Does FeSO4 dissolve in water?

Iron(II) sulfate/Soluble in
How is FeSO4 7H2O formed?
Ferrous sulphate BP, FeSO4,7H2O, dehydrates to form FeSO4,4H2O when the relative humidity (RH) is less than 65\%, or on heating at 40 degrees C. The tetrahydrate was also prepared by recrystallization at 60 degrees C from aqeuous solutions of the sulphate.
What is FeSO4 7H2O?
Iron(II) sulfate heptahydrate.

How does FeSO4 dissolve in water?
All Answers (1) I prepared 0.01 M FeSO4. 7H2O stock solution by adding 2.8g of the solid to 1 ml conc sulfuric acid, stir, then add to water. Dilute to 1 L.

How does ferrous sulphate dissolve in water?
Weigh 0.8 g of ferrous sulfate (dry weight basis), dissolve, and make up to 1 liter in a volumetric flask. Transfer the solution to a 1.5-liter beaker, add 1 N of NaOH dropwise with constant stirring to adjust to pH 6. Mix well, let stand for 1 hour, and filter through a GF/C filter (or equivalent) with vacuum.
