Hey Everyone!
Welcome to my channel LearNew. Where you can learn something new daily.

In this video I am gonna to explain

What is Acid Rain?
Acid rain describes any form of precipitation that contains high levels of nitric and sulfuric acids
Acid rain is a broad term that is often used to describe several forms of acid deposition. Wet deposition is when rain, snow, fog, or mist contains high amounts of sulfuric and nitric acid. Power stations, factories and cars all burn fossil fuels and therefore they all produce polluting gases. Some of these gases (especially nitrogen oxides and sulphur dioxide) react with the tiny droplets of water in clouds to form sulphuric and nitric acids. The rain from these clouds then falls as very weak acid - which is why it is known as "acid rain". Dry deposition of acid rain occurs when dust and smoke that contain high amounts of sulphur dioxide and nitrogen oxides settle to the ground, or onto buildings, cars and vegetation. These gases are converted to acids when they contact water. Normal rain is slightly acidic, with a pH value of 5.6, where Pure water has a pH of 7 while acid rain generally has a pH v5 between 4.2 and 4.4.

Acid rain has many ecological effects, especially on lakes, streams, wetlands, and other aquatic environments. Acid rain makes such waters more acidic, which results in more aluminum absorption from soil, which is carried into lakes and streams. That combination makes waters toxic to crayfish, clams, fish, and other aquatic animals.

Acid Rain Damages Buildings and Objects
It can also have a damaging effect on many objects, including buildings, statues, monuments, and cars. The chemicals found in acid rain can cause paint to peel and stone statues to begin to appear old and worn down, which reduces their value and beauty.
