how can someone explains acidic rain?

HOW ACID RAIN IS FORMED\n\nAcid rain is caused by the release of the gases SO2 (sulphur dioxide) and NOX (nitrous oxides). The main sources of SO2 in South Africa are coal-fired power stations and metal working industries. The main sources of NOX emissions are vehicles and fuel combustion.\n\nSulphur dioxide reacts with water vapour and sunlight to form sulphuric acid. Likewise NOX form nitric acid in the air. These reactions takes hours, or even days, during which polluted air may move hundreds of kilometres. Thus acid rain can fall far from the source of pollution. \n\nWhen mist or fog droplets condense they will remove pollutants from the air and can become more strongly acid than acid rain. Even snow can be acid. Gases and particles, not dissolved in water, with a low pH can also be deposited directly onto soil, grass and leaves. It is possible that even more acidity is deposited in this way than by rain! Not much is known about this process, and it is particularly difficult to study.\n\nhttp://www.botany.uwc.ac.za/Envfacts/facts/acidrain.htm\n\nhttp://www.botany.uwc.ac.za/Envfacts/facts/acidrain.htm

Rain.  you are describing the dewpoint.

I believe the classic way of showing the effects of acid rain is to use lime stone corrosion. Test the possibilities using a piece of limestone (chalk or similar), three different petrie dishes, on one use ordinary distilled water, the next with an alkaline solution the the third with acid and note the effects. The latter should start to bubble hence showing a reaction between the two. This has a huge knock on effect with buildings, cliffs, statues, etc as they are worn away by rain which has become acidic.

Because it is quite a mild solution. There's plenty more water than acid, therefore you may assume that the properties of the water haven't changed much.

Are you talking molecular level or physical process?\n\nWater is the bond between Hydrogen+ and two Oxygen- formulating H2O.\n\nWater as in the rain.  Evaporation is the water droplets from the sun heating up the water rising to the sky, also the plants perspire its water from the heating of the sun and rises to the sky, then condensation is the cooling of the droplets and condensing, weighs down the cloud with concentrated & heavier droplets and precipitation is the actually rain droplets falling to Earth.\n\nThe chemical process of cleaning the water to drink is the earthly cycle, but you want to go with human cleaning is the introduction of a sanitizing and killing bacteria in the water with chlorine and making it supposedly healthy with fluoride.  And a bunch of supposed microfilters to catch debris and bacteria.  Heating the water also helps clean it a little.

The same thing that causes prizms in crystals.  It is the colors of light, the rain condenses them just as the crystal does

i think it may be that SO2 will react with water to give sulphurous acid (H2SO3).  This is the common acid found in acid rain.  The concentrated ammonia may be to neutralise the acid should it be formed from the SO2 leak.\n\nPossibly anyway....

A complete answer to this question would require a very large book.  You will need better focus for a short answer.\n\nAcids dissolve most minerals and rocks.  Even water dissolves rocks or rock constituents over a long period of time.  There is fabulous erosion in calcium rich rocks creating tunnels and underground chambers...\n\nAcid rain enhances this process greatly.  Virtually all the salts in the oceans came by the erosion of rock salts over aeons of time spent under the never ceasing rainy seasons.\n\nSome conditions are rock forming or metamorphosing, others are rock dissolving.\n\nHeat and cold are also factors in the deterioration of rock, making it more vulnerable to water and acid rain.\n\nThere are many fabulous websites on rocks and minerals and gemstones.  Just Google some of that and you will pull up two or three super-excellent ones.\n\nTry also Googling "rock geological processes."  Keep it in quotes.

There are a lot of great sites that give basic weather predicting information.\n\nDifferences in air pressure are what causes the fronts--high and low pressure. High pressure areas generally have dry, good weather and areas of low pressure have precipitation.

All I know about freezing rain is that it hardens (freezes) once it hits the ground.

Problem State: \n68 million acres of forest damaged or destroyed by acid rain \n\nAcid rain is caused primarily by the emission of sulfur dioxide from coal-fired power plants. There are a number of remedies, including: switching fuel sources to natural gas, oil, or renewable energy sources; switching to low-sulfur coal; removing the sulfur from the coal before burning; using fluidized-bed combustion processes to burn the coal; and removing the sulfur from the smoke stack after combustion through the installation of pollution control equipment such as "scrubbers." \n\nCosts/Benefits \n\nA combination of tax incentives, government regulations and direct assistance that results in pollution-control equipment being placed on all coal combustion sites, increases in efficiency of industrial processes, transportation and appliances would cost approximately $8 billion per year for ten years. This is about 1% of the world's total military expenditures.

The effect of acid rain on Spirogyra-It is found that the concentrations of the sulfuic acid rain simulation damaged the Spirogyra cell structure to a greater degree than the nitric acid. Though the nitric acid rain simulation had\nsimilar damaging effects to cell structure and color, in both concentrations and pH levels, the sulfuric acid\nseemed to create greater cell damage and therefore would be considered more harmful to plant life.Sulfuric acid is more harmful to the cellular structureof Spirogyra than nitric acid. These findings are important because among other things, they show that acid rain negatively affects our ecosystem because it damages the most basic levels of the food chain and thus jeopardizes the higher forms of life. Acid rain also causes changes to the atmosphere, more\npollution, and damages trees, which absorb carbon dioxide and produce oxygen.

when it rains, it pours.\n\nHope you don't live on/near a hillside.

It is then Acid Rain. Not Good.

Winds pick up water vapor as they blow across oceans, and drop the water as rain as they blow across islands and  continents, generally losing more water as the elevation rises.  \n\nAs the air and clouds blow over higher ground, the temperature drops and causes the water to precipitate, forming rain.  There is a "rain shadow," on the leeward side of the higher ground in the center of an island or continent, because the clouds drop the rain on the "windward" side of a mountain (side toward the wind), leaving the "leeward" side drier (side that's sheltered from the wind).\n\nThe winds blowing across the ocean pick up water and bring rain to India, bringing more rain as they first come to the land, raining as the elevation rises, and then raining less after they cross the higher ground in the central parts of India. \n\nHope this helps.

the form just about everywhere in the world.  slightly acidic water (which most rain water is...it picks up CO2 on the way down....and makes a mild carbonic acid) dissolves limestone over long amounts of time.   it also happens with dolomite, marble, and gypsum....and it can happen with sandstone, as well - in the case of sandstone, carbonates act as a binder.
