Carbon dioxide is an essential component...

Carbon dioxide is an essential component of atmosphere. However, when the concentration of `CO_2` increases in the atmosphere, it can lead to global warming through green house effect. Similarly, rain water is an essential source of water. It has pH of 5.6 due to the formation of `H^+` ions from the reaction of rain water with `CO_2` present in the atmosphere. When pH of the rain water falls below 5.6 due to the presence of acids in the atmosphere, it has very damaging effects.
Why is acid rain considered as a threat to Taj Mahal in Agra ?

**Step-by-Step Solution:** 1. **Understanding Acid Rain**: Acid rain is formed when pollutants like sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) react with water vapor in the atmosphere, leading to the formation of sulfuric acid (H₂SO₄) and nitric acid (HNO₃). This results in rainwater with a pH lower than 5.6, making it acidic. 2. **Chemical Composition of Taj Mahal**: The Taj Mahal is primarily made of marble, which is chemically known as calcium carbonate (CaCO₃). 3. **Reaction of Acid Rain with Marble**: When acid rain, particularly containing sulfuric acid, falls on the marble of the Taj Mahal, a chemical reaction occurs. The reaction can be represented as: \[ ...

What is pH of rain water?

Assertion : Normally rain water has a pH of 5.6 Reason : H^(+) ions are formed by the reaction of rain water with carbon dioxide present in the air.

Assertion : Higher concentration of CO_2 in atmosphere is causing global warming. Reason : This is due to greenhouse effect.

Assertion: The pH of a rain water is 5.6 Reason: H^(+) ions are formed by the reaction of rain water with carbon dioxide present in the atmosphere.
