[amp_mcq option1=”Hydrogen sulphide” option2=”Carbon dioxide” option3=”Methane” option4=”Oxygen” correct=”option1″]<\/p>\n
The correct answer is A. Hydrogen sulphide.<\/p>\n
Lead acetate is a white solid that dissolves in water to form a colorless solution. When lead acetate solution is exposed to hydrogen sulfide, it forms a black precipitate of lead sulfide. This is a chemical reaction that can be used to test for the presence of hydrogen sulfide.<\/p>\n
Carbon dioxide, methane, and oxygen are all gases that are not likely to react with lead acetate. Therefore, if a paper moistened with lead acetate turns black when placed in a manhole, it is likely that the sewer contains hydrogen sulfide.<\/p>\n
Hydrogen sulfide is a colorless, flammable gas with a rotten egg smell. It is produced by the decomposition of organic matter, such as sewage. Hydrogen sulfide is toxic and can cause a number of health problems, including respiratory problems, nausea, and vomiting.<\/p>\n
If you are exposed to hydrogen sulfide, it is important to seek medical attention immediately.<\/p>\n","protected":false},"excerpt":{"rendered":"
