Which of the following is obtained upon heating ferrous sulphate?
Ferric oxide, sulphur dioxide and sulphur trioxide
The correct answer is option 3 i.e. Ferric oxide, sulphur dioxide and sulphur trioxide.
When ferrous sulphate is heated, it undergoes thermal decomposition. This process produces ferric oxide, sulphur dioxide, and sulphur trioxide as the main products. The green crystals of ferrous sulphate lose water molecules and turn white first. Upon further heating, it decomposes completely to give ferric oxide as a brown solid and releases both sulphur dioxide and sulphur trioxide gases. This is a classic example of decomposition reaction. The correct answer is ferric oxide, sulphur dioxide and sulphur trioxide. Every step shows the breakdown of ferrous sulphate into multiple simpler substances, which is a key property of thermal decomposition.
