Explain the process of heating ferrous sulphate (decomposition of ferrous sulphate crystals)
Answers
Answer :
Ferrous sulphate crystals(FeSO₄) are green in colour. When these crystals are heated they lose their water of crystallisation molecules and become anhydrous ferrous sulphate and their colour becomes white.
On further heating, these white coloured anhydrous ferrous sulphate decomposes into ferric oxide(Fe₂O₃), sulphur dioxide(SO₂) & sulphur trioxide(SO₃). This reaction is called decomposition reaction.
Hence, ferrous sulphate crystals finally became three simpler products upon decomposition - ferric oxide, sulphur dioxide & sulphur trioxide. Ferric oxide obtained here is reddish-brown in colour while the other two are gases. These gases are colourless and are poisonous too.
Reaction for the decomposition process :

Decomposition reaction :
A type of chemical reaction in which a single reactant splits/broke down into a number of simpler products is called a decongestant reaction. All decomposition reactions are endothermic and require energy in the form of heat, light or electricity to occur.
