Question

2 grams of ferrous sulphate crystals are heated.name the gases produced during heating
pls answer fast​

Answer 1

ferric oxide is formed

Answer 2

Answer:

2 g of ferrous sulphate crystals are heated in a boiling tube then  we observe that :

1 Ferrous sulphate crystals contains 2 water moelcules.

On heating it looses water molecules and becomes anhydrous ferrous sulphate .

2. Colour changes from  light green to white . Ferrous sulphate crystals  which are in green colour decomposes  to give Ferric oxide , sulphur dioxide and sulphur trioxide gas.

3. On further heating  FeSO4 anhydrous changes to dark brown solid ..

4. The gas emitted has the characteristics smell of sulphur.

Chemical reaction :.

2FeSO4 (S) -------------->Fe2O3 (S) +SO2(g) +SO3 (g)

Anhydrous                  Ferric oxide

Ferrous sulphate
