Ferrous sulphate on heating gives a solid product and two different gases. Select the gases evolved during the reaction.

Correct option is C

The correct answer is (C)     ​Sulphur dioxide and sulphur trioxide

• Ferrous Sulfate (FeSO₄): The chemical formula of ferrous sulfate is FeSO₄.
• When ferrous sulfate is strongly heated, it decomposes to form a brown solid (ferric oxide, Fe₂O₃) and releases two gases.
• This process is an example of a decomposition reaction, and the balanced equation is:

2FeS$$O_4$$ → F$$e_2$$$$O_3$$ + S$$O_2$$ + S$$O_3$$​​​

• The gases released are sulfur dioxide (SO₂) and sulfur trioxide (SO₃).
  

Information booster:

Oxygen (O₂):Oxygen can be produced through various processes like:

   Electrolysis of Water:   2$$H_2$$O → 2$$H_2$$ + $$O_2$$​​

• Thermal decomposition of specific oxides.
• Photosynthesis in plants.

Disulfur (S₂):Disulfur is formed when certain compounds like COS, S₂Cl₂, or CS₂ are exposed to UV light.

Sulfur Trioxide (SO₃):Sulfur trioxide is represented by the chemical formula SO₃.

Sulfur dioxide (SO₂) in the air can slowly oxidize to form sulfur trioxide:

S$$O_2$$ + $$\frac{1}{2}$$$$O_2$$ → S$$O_3$$​​​
