Assignment
Q 1-A student performed the experiment of heating ferrous sulphate in a
boiling tube. He felt fumes of a pungent gas and saw colours of ferrous
sulphate disappeared.
a) Write the chemical formula of the pungent gases.
b) Why does the colour of crystal disappear?
c) Identify the nature of this chemical reaction.​

Answer 1

Answer:

Explanation:

The pungent smelling gas is sulphur dioxide and some amount of sulphur trioxide also gives some amount to the smell.

The colour of the crystal changes from green to brown as the water molecules from the compound loses and it turns immediately brown as it forms ferric oxide.

The gases evolve when ferrous sulphate is heated in a boiling flask the water molecules break down giving rise to ferrous sulphate which undergoes decomposition reaction to give sulphur dioxide and trioxide and ferric oxide.
