Questions & Answers

Q: What is a decomposition reaction?

A decomposition reaction is when a compound breaks down into simpler substances, which can occur due to heating, chemical reactions, or other factors.

Q: What happens to ferrous sulfate during a decomposition reaction?

When ferrous sulfate is heated, it undergoes a decomposition reaction, changing its color from green to white and then to reddish brown due to the formation of ferric oxide.

Q: What gases are released during the decomposition of ferrous sulfate?

Sulfur dioxide and sulfur trioxide gases are released during the decomposition of ferrous sulfate, resulting in a pungent and rotten smell due to the burning of sulfur.

Q: Are the released gases during the decomposition reaction of ferrous sulfate harmful?

Yes, the sulfur dioxide and sulfur trioxide gases released during the decomposition of ferrous sulfate are toxic and should not be inhaled, as they can cause harm to the respiratory system.

Summary & Key Takeaways

• A decomposition reaction occurs when a compound breaks down into two or more simpler substances, as shown by the example of ferrous sulfate.

• Ferrous sulfate crystals have a green color, but when heated, they change to white and then to reddish brown due to the formation of ferric oxide.

• During this reaction, sulfur dioxide and sulfur trioxide gases are released, which have a pungent smell and are toxic if inhaled.
