Question

What is the cause of acid rain? Give any two impacts of acid rain.

Answer 1

Hint: Acid rain is the rain water containing the harmful chemicals like nitrogen oxides and Sulphur oxides. The chemicals or industrial effluents from the industries in the vapor state enters into the atmosphere and converts into oxides and dissolves with the water vapor and occurs as acid rain.

Complete answer:
Industries release effluents into the atmosphere. Vehicles release certain harmful gases into the atmosphere. These chemicals include nitrogen and Sulphur oxides. When these oxides dissolve in rainwater, certain mineral acids will be formed. These acids include carbonic acid, nitric acid and sulphonic acid.
These acids will be dissolved in acids and make the rain water acidic.
So. The industrial effluents and chemicals released from the vehicles were responsible for the cause of acid rain.
There were severe impacts of acid rain. These include the following:
The aquatic life will be destroyed as the acidic rain increases the acidity present in lakes and seas.
The acid rain makes the soil lose its fertility, as the ions like potassium and sodium can be lost from the soil.
The humans will also get health and skin diseases when the acid rain gets contact with the human body.

Note:
The acid rain is mainly caused by the industrial effluents and chemicals. The pH of the rain water is less than the normal fresh water which means it is more acidic. The monuments like Taj Mahal can be destroyed by acid rain due to more acidic water in acid rain.
