Explanation:

Answer 2

Answer:

The assertion 'On heating the colour of ferrous sulphate crystals changes from green to white' and the reason ' When ferrous sulfate crystals are heated there is a loss of molecules of water of crystallisation' are correct.

Explantion:

Assertion: On heating the colour of ferrous sulphate crystals changes from green to white.

The crystals of ferrous sulphate are green- $FeSO_{4}.7H_{2}O$. Upon heating it turns white and then later reddish brown.

Reason: When ferrous sulfate crystals are heated there is a loss of molecules of water of crystallisation.​

The hydrated crystals lose their water on heating and turn white from green. Further heating, produces ferric oxide, sulphur dioxide and sulphur trioxide. Ferric oxide is reddish brown in color.

$FeSO_{4}.7H_{2}O +$Δ→$Fe_{2}SO_{3} + SO_{2} + SO_{3}$

Conclusion:

The assertion and its reason are correct.
