Question

what is acid rain?

were does it accour?

what was the most famous place were acid rain took place?

how can we prevent it?

Answer 1

Acid rain is any form of precipitation(rain, snow,sleet,fog, etc)which contains high levels of acid.Precisely,it is precipitation with dilute solutions of two strong acids--sulphuric and nitric.Both sulphur and nitrogen emissions are attributed to the burning of fossil fuels particularly high-sulphur coal and oil and particularly the use of the latter has increased due to industrial development.There has been a rise in carbon dioxide and sulphur and nitrogen oxides in the last 150 years during which fossil fuel consumption has increased.

In acid rain,which contains sulphuric acid,the first ingredient is the sulphur dioxide gas emitted by power stations,cars and lorries.When it meets the highly reactive chemical agents called OH radicals in the atmosphere,it is oxidised to form sulphur trioxide which is also a gas.This then combines with rain water to form sulphuric acid.

The pH value of pure rain water is about 7;but in the acid rain it becomes less than 4.In industrially advanced cities like Toronto and Los angels of the USA,the average pH value of rainfall becomes 3.5 and 2.2 respectively.

The most acidic rainfall recorded in the USA  with a pH value of 1.4 is in West Virgenia.

Avoiding using fossil fuels is the only way to reduce the acid rain which is not possible in the near future.

Answer 2

Acid Rain is precipitation that is acidic due to pollution and chemicals in the atmosphere that the rain and water vapor picks up on the way down. It tends to happen where there are a lot of fossil fuel burning industries are and can kill a lot of forest areas, stripping the trees of its vegetation.

Most famous place, I believe was in the Appalachians...

And we prevent this by polluting less....
