Marks:
+1,
-0
Solution:
The correct answer is 1, 2 and 3.
- Sources of compounds causing acid rain:
- Sulphur
- Natural Resources
- Seas and oceans
- Volcanic eruptions
- Biological process in the soil e.g., Decomposition of Organic matter
- Man-made sources:
- burning of coal (60%)
- Petroleum products (30 % of S02) and smelting of metal sulfides ores to obtain the pure metals
- Industrial production of sulphuric acid in metallurgical, chemical, and fertilizers industries.
- Nitrogen
- Natural Resources
- Lightning
- Volcanic eruptions
- Anthropogenic sources:
- Forest fires
- Combustion of Oil, Coal, And Gas
- Formic acid
- Biomass burning due to forest fires causes the emission of formic acid (HCOOH) and formaldehyde (HCHO) into the atmosphere.
- Large fraction formaldehyde gets photo-oxidation and forms formic acid in the atmosphere.
- These are the main compounds that cause the acidification of rain in the atmosphere.
- Other Acids:
- Chlorine
- Phosphoric Acid
- Hydrochloric acid (smokestacks)
- Carbon monoxide and carbon dioxide. These become carbonic acids.
- Hence option 1 is correct.
