Acid rain is due to:
Correct answer: D. All of these
- A. Formation of oxides of sulphur
- B. Formation of oxides of nitrogen
- C. Formation of H2SO4 and HNO3
- D. All of these
Explanation
Acid rain is primarily caused by the emission of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere. These gases react with water, oxygen, and other chemicals to form sulfuric acid (H2SO4) and nitric acid (HNO3), which then fall to the earth as acid rain.

About Environmental Chemistry
Atmospheric pollution includes smog, acid rain, greenhouse gases, ozone depletion and the effects of carbon monoxide, sulfur oxides, nitrogen oxides and particulate matter. Water pollution covers sewage, industrial waste, eutrophication and treatment stages, while green chemistry focuses on reducing hazardous substances, waste and energy use through safer, more efficient processes.
