Question
The primary cause of rainwater around the world having a pH lower than 7 isa.Bromineb.carbon dioxidec.sulfur dioxided.Methane
Solution
The primary cause of rainwater around the world having a pH lower than 7 is carbon dioxide. Here's why:
- When rainwater falls through the atmosphere, it interacts with gases present in the atmosphere.
- One of these gases is carbon dioxide (CO2).
- The rainwater and carbon dioxide react together to form carbonic acid (H2CO3), a weak acid.
- This acid lowers the pH of the rainwater, making it slightly acidic (pH less than 7).
- Therefore, the primary cause of rainwater around the world having a pH lower than 7 is carbon dioxide.
Note: While sulfur dioxide and nitrogen oxides from pollution can also contribute to acid rain (which has a pH of less than 5.6), under normal conditions, it's the carbon dioxide that causes rainwater to be slightly acidic.

In acid rain, the pH of rain water falls belowQuestion 11AnswerA.6.2B.7C.5.6D.6
Rainwater was collected at thirty different sites near an industrial basin and the amount of acidity (pH level) was measured. The pH values were:2.6, 2.7, 2.9, 3.2, 3.3, 3.7, 3.7, 3.8, 3.9, 4.1, 4.2, 4.2, 4.2, 4.4, 4.4,4.6, 4.8, 4.9, 4.9, 5.0, 5.5, 5.5, 5.6, 5.7, 5.8, 5.8, 6.0, 6.2 6.3, 6.3The interquartile range is:
