Answer:
(i) The colour of
ferrous sulphate crystals is green. On heating, FeSO4.7H2O
first decomposes to form anhydrous ferrous sulphate (FeSO4) which is
white in colour.
(ii) The products formed on strongly heating ferrous sulphate
crystals are ferric oxide, sulphur dioxide and sulphur trioxide.
This is a type of decomposition reaction (thermal
decomposition).
