Question

what is colour of ferrous sulphate crystal how does this colour change after heating name the product formed on strongly heating process is a crystal what type of chemical reaction occur in this write chemical equation of the reaction

Answer 1

The ferrous sulphate crystals are light green in colour. The gas emitted has the characteristic odour of burning sulphur. On heating, the colour changes from light green to white. On further heating, the white substance changes to dark brown solid.

On strongly heating ferrous sulphate crystals;ferric oxide,sulphur dioxide and sulphur trioxide are formed.
