【Daily Question】11.23 True or False: The intensity of the rotten egg smell of hydrogen sulfide is directly proportional to its concentration. ( ) Answer: Wrong
Wrong; it seems to lose its flavor once it exceeds 30
Wrong. It can be detected at low concentrations, and the stronger the concentration, the more intense the smell ； At high concentrations, human sense of smell can no longer distinguish smells due to hydrogen sulfide paralyzing the nerves.
Wrong. When the concentration is high, no odor can be detected.

The intensity of the rotten egg smell of hydrogen sulfide is directly proportional to its concentration. (Mistake)

The intensity of the rotten egg smell of hydrogen sulfide is directly proportional to its concentration. ( Wrong )
Wrong. Hydrogen sulfide is a colorless, **, acidic gas. There is a distinct smell of rotten eggs; the olfactory threshold is 0.00041 ppm, and even low concentrations of hydrogen sulfide can damage human sense of smell. At high concentrations, there is no odor (because high concentrations of hydrogen sulfide can numb the olfactory nerves). Using the nose as a means to detect this gas is fatal.
The intensity of the rotten egg smell of hydrogen sulfide is directly proportional to its concentration. (Correct)
