Question

On heating the pale green coloured crystal of ferrous sulphate undergo decomposition. A mixture of _ _ _ and _ _ _ gases formed

Answer 1

Answer:

On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white. On further heating, anhydrous ferrous sulphate decomposes to form ferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur trioxide (SO3)

Answer 2

Answer:

ferric oxide and sulphate oxide and sulphide oxide gases will form

Explanation:

On heating at first the colour of ferrous sulphate disappears i.e. it becomes anhydrous and heating strongly we obtain ferric oxide and sulphate oxide and sulphide oxide gases
