The emission of brown fumes in the given experimental set-up is due to
Options
The emission of brown fumes in the given experimental set-up is due to thermal decomposition of lead nitrate which produces brown fumes of nitrogen dioxide.
Marking Scheme
- 11 mark for correct answer
Hint
The brown fumes emitted during the reaction are a key indicator of the formation of nitrogen dioxide gas.
Quick Oral Answer
The emission of brown fumes in the given experimental set-up is due to thermal decomposition of lead nitrate which produces brown fumes of nitrogen dioxide.
Analysis & Explanation
The correct answer is option (a) because the thermal decomposition of lead nitrate produces brown fumes of nitrogen dioxide. The other options are incorrect because they do not accurately describe the reaction or the products formed.
Common Mistakes
- 1confusing the reaction with oxidation of lead nitrate
- 2misidentifying the products formed
Interesting Facts
Lead nitrate is a strong oxidizing agent and can cause burns if not handled properly.
Nitrogen dioxide is a toxic gas and can cause respiratory problems if inhaled in large quantities.
