Ferrous sulphate crystals is to be heated
2FeSo4 - Fe2O3 + So2 + So3
Feso4 - ferrous sulphate green colour
Fe2o3 - ferricoxide red colour
Obeservation - 1) green colour of ferrous sulphate crystals changes to red colour due to ferric oxide
2) rotten egg smell due to so2
Ferrous sulphate crystals losses h2o when heated and colour of crystals changes
