MCQ
Which of the following does not contribute to acid rain?
- ANitrogen monoxide.
- BSulphur dioxide.
- ✓Carbon monoxide.
- DCarbon dioxide.
✓
Answer
Correct option: C.
Carbon monoxide.
Acid rain is caused by emissions of sulphur dioxide, carbon dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce sulphurous acid, carbonic acid and nitric acid respectively.
Acid rain is rain or any other form of precipitation that is unusually acidic and it possesses higher levels of hydrogen ions $($low $\ce{pH})$.
