Rainwater is not actually getting less acidic. it is actually getting more acidic! the more greenhouse gases we use (e.g: carbon dioxide) the more acidic our rain gets! This occurs because the more fossil fuels and greenhouse gases get thrown carelessly into the oceans, lakes and rivers; the more acidic they get. This means that when the water evaporates into the air, it is more acidic then it's usual neutral (7 on the pH scale). This is also affecting global warming and killing the sea animals by taking all the oxygen from the water and replacing it with harmful substances.
Carbon dioxide in the atmosphere is dissolved in water, making natural rainwater slightly acidic, so when other gases such as sulphur dioxide are dissolved in rainwater, it becomes more acidic than it would be if it didn't contain carbonic acid.
The more acidic of two acidic solutions has more H+ ions per liter.
There are two reasons for rain water being slightly acidic:some (weakly) acid forming CO2 from air is dissolved in itother air pollutants like SO2 and nitric oxides (cars, indusry, smog) are even stronger acid forming
Lemon Juice is more acidic.
The rainwater is more acidic after passing through polluted air.
As rainwater falls to earth, it absorbs pollution (natural and industrial) in the atmosphere which turns the rainwater slightly acidic. Limestone is affected by the acidity, and weathering and erosion is the result. The more pollution, the stronger the acidity, and the more damage is done to buildings and statues made from limestone.
salt salt makes it more acidic
Sulfuric acid
Depends where you are - if there is a lot more industry to your east, then yes.
By burn coal,coal release sulphur to atmosphere

No. Rainwater is usually slightly acidic because of the carbon dioxide dissolved in it. Sometimes, it can be strongly acidic, if pollutants like sulphur dioxide and nitrogen dioxide are dissolved in it. Both weakly and strongly acidic rainwater react with some rocks, but only ones that are alkaline. Chalk is almost pure calcium carbonate and reacts fairly quickly with rainwater. Other rocks that contain calcium carbonate include limestone and marble and these react a little more slowly. But some rocks, like sandstone, are actually acidic and don't react with rainwater (though they are still physically weathered by rain). Granite also doesn't react with rainwater and it physically weathers much more slowly.
because we started burning more and more coal and that is all what acid rain is is pouted water
This depends on the zone: sometimes the groundwater is polluted or the rain water is acidic and contain particles collected from the atmosphere.
Not very good. The rain nowadays are more acidic than neutral, and if you swim in a pool of rainwater too much, it is bad for your skin and hair. And if you swallow it, the effects might be minor but slowly, you'll get sicker and catch colds.
Because of their chemical composition, feldspars are more easily attacked by mildly acidic rainwater than say a quartz would be.
