Question

What happens when ferrous sulphate crystals are strongly heated

Answer 1

when FeSO4 crysatals are heated , they form their anhydrous FeSO4 and hence , their colour changes from green to white.


   hope this helps u........

Answer 2

Answer: This leads to the production of ferric oxide, sulfur dioxide and sulfur trioxide.

Explanation:

Ferrous sulfate crystals are green in color. It is present in hydrated form and when it is heated, the hydrated ferrous sulfate forms anhydrous ferrous sulfate which is white in color.

$FeSO_4.7H_2O\rightarrow FeSO_4(s)+7H_2O$

On strong heating, the products obtained are ferric oxide, sulfur dioxide and sulfur trioxide.

$2FeSO_4(s)\xrightarrow[]{Heat}Fe_2O_3(s)+SO_2(g)+SO_3(g)$
