Question

13. List any two observations when Ferrous Sulphate is heated in a dry test tube.​

Answer 1

Answer:

Following two observations are observed when crystals of ferrous sulphate are heated: (1) Change in state and color takes place. (2) A gas is evolved during this process.

Explanation:

Since, the compound (ferrous sulphate) decomposes into two or more substances therefore, it is a decomposition reaction.

Answer 2

Answer:

7H2O). On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white. On further heating, anhydrous ferrous sulphate decomposes to form ferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur trioxide (SO3)
