Question

(i)What is the colour of ferrous sulphate crystals? How does this colour change after heating?
(ii)Name the products formed on strongly heating ferrous sulphate crystals. What type of chemical reaction occurs in this change?
Answer:

Answer 1

(i)The colour of ferrous sulphate is Green.
When Fe(SO4)====>Fe2O3+SO2+SO3
[Ferrous sulphate][Ferric [sulphur
oxide] dioxide]
Green======>Reddish brown.

(ii)When we heat Ferrous sulphate[Fe(SO4)],we get Ferric oxide[Fe2O3] +SO2+SO3
The chemical reaction occurs in this change is Decompostion chemical reaction.

Hope it helps

Answer 2

HEY DEAR.....
HERE'S YOUR ANSWER....
(i)Ferrous sulphate crystals are light green in colour. This is because of the presence of water molecules(FeSo4.7H2O ferrous sulphate heptahydrate).On heating, the water molecules evoperates and the green coloredcrystals turn White.
(ii) On heating these crystals, they become White and on further heating......they turn to brown colour.i.e.On further heating anhydrous ferrous sulphate decomposes to form ferric oxide(Fe2O3), Sulphur dioxide (SO2), and Sulphur trioxide (SO3).
