When the quantity of acids in the raining water is more than the average, then such rain is called 'Acid rain'.

We are aware that normally rainwater has a pH of 5.6. When the pH of the rainwater drops below 5.6, it is called acid rain.

Acid rain refers to the ways in which acid from the atmosphere is deposited on the earth’s surface. Oxides of nitrogen and sulphur which are acidic in nature can be blown by the wind along with solid particles in the atmosphere and finally settle down either on the ground as dry deposition or in water, fog and snow as wet deposition.

Acid rain is a byproduct of a variety of human activities that emit the oxides of sulphur and nitrogen in the atmosphere. As mentioned earlier, burning of fossil fuels (which contain sulphur and nitrogenous matter) such as coal and oil in power stations and furnaces or petrol and diesel in motor engines produce sulphur dioxide and nitrogen oxides.

SO₂ and NO₂ after oxidation and reaction with water are major contributors to acid rain because polluted air usually contains particulate matter that catalyses the oxidation.

2SO₂ (g) + O₂ (g) + 2H₂O (l) → 2H₂SO₄ (aq)

4NO₂ (g) + O₂(g)+ 2H₂O (l) → 4HNO₃ (aq)

The bad effects of acid rain

When acid rain falls and flows as groundwater to reach rivers, lakes etc, it affects plants and animal life in the aquatic ecosystem
Acid rain is harmful to agriculture, trees,.. and plants as it dissolves and washes away nutrients needed for their growth.

The jailor then asked each prisoner to secretly open the boxes and look at the currency inside. He then said three of you have a box containing Indian Rupees; two of you have a box containing US Dollars, I shall now give each one of you a chit containing information about the box of exactly one other person. He did so and asked them to open the chit and see the information provided to them. Jailor again said None of you will be able to tell the exact currency of any third person. Then he announced Bach has a box containing Indian Rupees Aristotle immediately said I Know the currency of all 5 people.
