Observations:
- Liquid droplets collected on the parts of the test tube
- Odour observed on heating ferrous sulphate crystals
- Successive colour change
- Products formed on heating ferrous sulphate crystals
- Type of reaction taking place

Identify the liquid droplets:
The liquid droplets collected on the parts of the test tube are water vapour. When ferrous sulphate crystals are heated, they lose their water of crystallization, which is released as water vapour. This process is known as dehydration.

Odour observed:
The odour observed on heating ferrous sulphate crystals is that of burning sulphur. This odour is due to the decomposition of ferrous sulphate crystals and the release of sulphur dioxide gas.

Successive colour change:
Initially, ferrous sulphate crystals are pale green in colour. As they are heated, they turn white due to the loss of water of crystallization. Further heating causes the white crystals to turn yellow due to the formation of ferric oxide.

Products formed:
The products formed on heating ferrous sulphate crystals are ferric oxide (Fe2O3), sulphur dioxide (SO2), and water vapour (H2O).

Type of reaction:
The reaction taking place here is a chemical reaction known as thermal decomposition. In this reaction, ferrous sulphate crystals decompose into different products when heated. The chemical equation for this reaction is:
2FeSO4(s) → Fe2O3(s) + SO2(g) + SO3(g)
