Question

Take about 2 g ferrous sulphate crystals in a dry boiling tube. Heat the boiling tube over
the flame of a burner or spirit lamp. In this reaction you can observe that a single
reactant breaks down to give simpler products. This is a decomposition reaction.
Ferrous sulphate crystals (FeSO4, 7H2O) lose water when heated and the colour of the
crystals changes. It then decomposes to ferric oxide (Fe2O3), sulphur dioxide (SO2)
and sulphur trioxide (SO3). Ferric oxide is a solid, while SO2 and SO3 are gases.
1.What can we observe in this activity?

Answer 1

Answer:

decomposition reaction
