Question

10. When ferrous sulphate is heated strongly it undergoes decomposition to form ferric oxide as a
main product accompanied by a change in colour from:
a. Blue to green. b. Green to blue.
C Green to brown. d. Green to yellow.​

Answer 1

Answer:

When ferrous sulfate is heated strongly the color changes from green to yellow

Explanation:

When ferrous sulfate is heated strongly it undergoes decomposition to form ferric oxide as a main product accompanied by a change in color from green to yellow.

The color of ferrous sulphate crystals are green and after heating, the color becomes white (pale yellow). On heating ferrous sulphate crystals at high temperatures, the products formed are ferric oxide, sulphur dioxide and sulfur trioxide.

The reaction for the decomposition of ferrous sulfate is below -

$2FeSO_4 +$ Δ → $Fe_2O_3 + SO_2 + SO_3$

The reason of color change on heating is that ferrous sulfate lose water  and anhydrous ferrous sulfate ($FeSO_4$) is formed.

So, the correct option is (d)

Answer 2

Answer:

The answer is (d) green to yellow

Explanation:

BECAUSE

HEAT

2FeSO4 ---------> Fe2O3 + SO2 + SO3

The reason of color change on heating is that ferrous sulfate lose water and anhydrous ferrous sulfate (FeSO4) is formed.

So the correct answer is option (d)
