Shahna took a small amount of lead nitrate in a dry test tube, holding the test tube with a test-tube holder. She put the test tube over the flame of the burner, and heated it. Soon a brown gas with a pungent smell is produced. The gas turns blue litmus red. She also observes a yellow solid residue remains in the test tube.
Q. Conclusion of the above experiment may be:
  • a)
    The brown gas evolved was nitrogen dioxide which is acidic in nature. The residue was yellow solid of lead oxide
  • b)
    The brown gas evolved was lead oxide which is acidic in nature. The residue was the yellow solid of nitrogen dioxide
  • c)
    The brown gas evolved was acidic in nature. The residue was the yellow solid of nitrogen dioxide
  • d)
    None of the above is a correct conclusion
Correct answer is option 'A'. Can you explain this answer?

To analyze the given experiment and draw a conclusion, we need to consider the observations and their implications. Let's break it down step by step:
Observations:
1. A small amount of lead nitrate was taken in a dry test tube.
2. The test tube was heated over a flame.
3. A brown gas with a pungent smell was produced.
4. The gas turned blue litmus red.
5. A yellow solid residue remained in the test tube.
Analysis:
1. Heating lead nitrate (Pb(NO3)2) can cause it to decompose and release various gases.
2. The brown gas with a pungent smell is likely to be nitrogen dioxide (NO2), which is a common product of the decomposition of lead nitrate.
3. Nitrogen dioxide is acidic in nature, which is supported by the observation that it turns blue litmus red.
4. The yellow solid residue is most likely lead oxide (PbO), which is a product of the decomposition of lead nitrate.
Conclusion:
Based on the observations and analysis, the correct conclusion of the experiment is:
The brown gas evolved was nitrogen dioxide (NO2), which is acidic in nature. The residue was the yellow solid of lead oxide (PbO).
Therefore, the answer is A: The brown gas evolved was nitrogen dioxide which is acidic in nature. The residue was the yellow solid of lead oxide.
