The color of crystals will change after heating because of loss of water..
When ferrous sulphate crystals are heated, they lose water of crystallization and turn into anhydrous ferrous sulphate. The balanced chemical equation for this process is: FeSO4 • 7H2O (s) → FeSO4 (s) + 7H2O (g)
The residue obtained when crystals of ferrous sulphate are strongly heated is reddish-brown in color. This residue is a compound called ferric oxide or iron(III) oxide.
When ferrous sulfate crystals are heated in a boiling tube with a spirit lamp, they undergo thermal decomposition. The crystals lose water of crystallization and change color from green to white as they form anhydrous ferrous sulfate. This reaction releases water vapor and sulfur dioxide gas.
Ferrous sulfate crystals produce a sulfuric, metallic smell when heated due to the release of sulfur dioxide gas. This smell is often described as pungent and unpleasant.
When ferrous sulfate heptahydrate crystals (FeSO4·7H2O) are heated, they undergo a dehydration reaction to form anhydrous ferrous sulfate (FeSO4) and water vapor (H2O). The chemical equation for this reaction is: FeSO4·7H2O(s) → FeSO4(s) + 7H2O(g)

2FeSO4 -> FeS + SO3 + SO4
Ferrous sulfate crystals produce a sulfuric, metallic smell when heated due to the release of sulfur dioxide gas. This smell is often described as pungent and unpleasant.
ferrous sulphate when it is heated it changes into red brown color
When ferrous sulfate heptahydrate crystals (FeSO4·7H2O) are heated, they undergo a dehydration reaction to form anhydrous ferrous sulfate (FeSO4) and water vapor (H2O). The chemical equation for this reaction is: FeSO4·7H2O(s) → FeSO4(s) + 7H2O(g)
When ferrous sulfate crystals are strongly heated, they decompose to form ferric oxide (Fe2O3), sulfur dioxide (SO2), and sulfur trioxide (SO3). The reaction involves the break down of ferrous sulfate into its constituent elements under high heat.
When ferrous sulphate is heated, it undergoes thermal decomposition to form ferric oxide, sulfur dioxide, and sulfur trioxide. The balanced chemical equation for this reaction is: FeSO4 (s) → Fe2O3 (s) + SO2 (g) + SO3 (g)
When hydrated ferrous sulfate is heated, it loses its water molecules and undergoes thermal decomposition. The color change is from pale green (hydrated) to white (anhydrous).
When ferrous sulfate is heated strongly, it undergoes thermal decomposition, breaking down into iron oxide, sulfur dioxide, and sulfur trioxide. This reaction is characterized by a color change from green to reddish-brown due to the formation of iron oxide.
Hydrous copper sulphate, when heated, turns into anhydrous copper sulphate and changes its color from blue to white. The blue color comes from the water molecules bound to the copper sulphate crystals, and when heated, these water molecules are removed, resulting in a color change.
