I m a student of bachelor in chemistry and our teacher assigned us a topics about acid rain influence. So I have prepared a material, but can't resist myself from writing whatever I learnt. Guy's the interesting facts if I tell you is that the chemistry is everywhere, all the things either living or nonliving product whatever you seen practical Life chemistry is there. Pharmaceutical, petroleum, cosmetics, food whatever the food you see , major constituents are the basic elements like carbon , hydrogen, Oxygen and nitrogen etc which are the building block elements. So lets talk about Acid rain

Acid rain:

• The Process involved in acid deposition, Sulphur oxides, nitrogen oxides and Hydrogen chloride gas play significant role in acid rain. This gases are produced by human activities mostly by the combustion of fossil fuels

Normal rain water has pH between 6.5-8.5, but in acid rain the pH reduced to 4-5 on average. Acid rain has adverse impacts on forest, aquatic life , old architectures and soils it cause paint to peel, corrosion of steel structure such as bridges.

Causes of acid rain:

Normal rain water is weekly acidic because of the absorption of carbon dioxide gas from the atmosphere and produces carbonic acid. When some gaseous oxides such as NO2, SO2, and Hydrogen chloride gas are mixed with rain water and come down from the atmosphere on the earth , that's Acid rain. Two main cause of acid rain in environment are:

• Acid rain due to natural causes.

• Man-made causes of acid rain.

Natural causes are : ignition of volcanoes and Forest fire release gaseous SO2 and NO2 into the air. NO2 oxides is formed by the reaction of atmospheric N2 and O2 at the time of lightning. Oxides of Nitrogen is also formed due to the dissociation of nitrogenous compounds of soil by soil bacteria and entered into the atmosphere. Man-made sources: the main man-made sources of SO2 and NO2 are , thermal station, acid production industry, motor vehicles , oil refineries and many more sectors.

Acid rain is caused when these pollutants are enter in air, these oxides are directly combined with the rain water and produced different mineral acids such as sulfuric acid, hydrochloric acid and nitric acid and falls on earth in form of acid Rain.

HCL gas from the hydrogen chloride manufacturing industry entered into the air. A volatile gas and highly water soluble substance. So it is readily dissolve in rain water and form Hydrochloric acid that falls on surface of earth as acid rain.contribution of sulfuric acid 62-65% and nitric acid 32-35% , hydrochloric acid 2% and nitrous acid 0-2%.

Effect of acid rain on environment:

Acid Rain is corrosive in nature and it can damage everything when comes in its contact as it contains sulfuric acid, nitric acid and hydrochloric acid. Acid rain has harmful effects on both plants and animals either completely or partially.

• Acid rain effect on soil

• Acid rain effect on aquatic life

• Acid rain effect on architecture and sculpture.

• Acid rain effect on human health

Acid rain effect on soil

Increase acid of the soil, as the result solubility of Metal and meta salt's present in the soil is changed because of acid Rain. This reduces the fertility of the soil than crop yields also decrease drastically. Plants face problem in Photosynthesis because leaves of the plants or trees burn and curl due to acid rain, plants growth decrease.

Acid rain effect on aquatic life

The reservoir has a specified pH value under which aquatic animals are live and when the acidity of reservoir will increase it will put drastic impact on the Aquatic life. If the acidity increase too much than the growth 9f fish aquatic animals and algae will decrease and ultimate death of aquatic organisms.

Acid rain effect on Architecture and sculpture

Memorial building that made of marble and lime Stone are effecting there shape became dull Day after a day because of acid rain. Tajmahal , Victoria memorial, Lalkila , historical architectures worsely effected by acid rain. When acid rain come in contact with these architectures , it reacts with lime stone or marble to cause wounds on buildings by forming calcium sulfate and calcium nitrate compounds.

Acid rain effect on human health

Damaging effect of acid rain directly or indirectly various harmful metallic substances dissolve in water of acid rain, these chemical substances enter human body through water results in severe damage of nervous, respiratory and digestive system. Acid rain also damage human skin , hair and cells , it causes irritation of skin.

Acid rain pollution can be prevented!

• Switch over to renewable sources of energy like wind and solar energy.

• Energy conversation should be prioritized by making sure no lights or appliances are left turned on after use.

• Alternative modes of traveling should he considered, like public transport.

• Sulphur free fuel and coal should be used. There should be decrease in emissions of SO2 and NO2 gas into the surrounding.
