Question

2kg of ferrous sulphte crystals are heated in a dry boiling tube. Name the chemical reaction taking place , what is the chemical equation for the reaction

Answer 1

Answer:

a) Observations :-

(i) Colour of the compound changes from green to white which on further heating changes to dark brown.

(ii) Evolution gas (SO_{2}/SO_{3}) and formation of raddish brown ferric oxide (Fe_{2}O_{3}).

(b) Decomposition Reaction take place.

(c) 2FeSO_{4}\overset{Heat}{\rightarrow}\underset{ferric oxide}{Fe_{2}O_{3}}+\underset{Sulphur dioxide}{SO_{2}}+\underset{sulphur trioxide}{SO_{3}}
