Rain brings down the crap in the air

Doesn't all that acid get removed from the air in the first hour of rain? Besides, I don't live in a city.
Is the rain that acidic in the country too?
Hours and days after the first rain?
That's a LOT of acid if it lasts for days of rain and hasn't come out.
But if it hasn't come out after days of rain, how much can be in rain?
Call me confused because I'm not saying you're wrong as I don't know.
But it doesn't add up right to me.

Depends where you live. If you are downwind from a coal fired steel
mill or power plant it could be worse.
Does it snow where you live? Take a look at the purity after it sits
and collects everything for a while. If you leave the windows open do
you get dust in the house?
Why do they put air filters on cars?

Look at the color of snow when a deep layer is mostly melted away.
It's a real thing and concentration (pH value) varies both
locally and over time:

Thank you for that link which showed in the first 99% that chemistry is
hard, but in the last 1% showed chemistry is easy with its conclusion.
What it said, in effect, if I understood what it said that is, is that rainwater is naturally carbonated to about pH 5.6 by CO2 in the air.
It says that means if the rainwater is lower than pH 5.6, only then is it considered to be acid rain. If it's pH 5.6 or above, it's not acid rain.
Seems simple enough.
I think they sell test strips somewhere where the plan based on that information is if the pH is below 5.6 then it's acid rain water.
Another question to ask is whether it really matters for what people use distilled water for, which for me is the cooling system, summer windshield washer mix (a drop of dish detergent is added to the full fill) and steam iron.
What else than that do you use distilled water for around the home & car? Does it matter for what you use distilled water around the home & car?
I have a friend who visits and he only drinks distilled water, plus I
use it for the car battery and used to actually do ironing.

Yes, and no. Distilled water is purified in a *contained environment* Rainwater can be *contaminated* by atmospheric dust, chemical
contaminants, etc.
It really depends on where you live whether your rainwater can be
considered the same as distilled water. If you live near, say, Bejing,
China, your rainwater might well be toxic. After all, the air in Bejing
is toxic.
Oh, did I mention dust and other pollutants on the roof and in the rain guttering? The rain water will gather these up in the process of washing
your roof and deposit them into the rainwater tank.

If there is CO2 in the air, it will acidify the rain. Guess what - there
is more and more CO2 in the air every year. The more CO2, (and NO2 and
SO2) the more acidity. One rain does not take it all away, as only so
much CO2 dissolves into any volume of water at any given temperature,
leaving most of the CO2 still in the air, waiting for more rain to carry
it down. (More at lower temps)
And, a warmer atmosphere holds more moisture, so there will be even more lower-pH rain.
Put a small puddle of rainwater on a piece of glass, then let it evaporate inside in a clean and dry place. Does it leave any residue? Does it leave
a whole lot of residue? Does it leave corrosive residue?

You'd need a lot more than a puddle to see the deposits, although you could >run that experiment with a glass tea kettle to boil the rainwater dry.

While pH 5.6 is acidic, it's mostly carbonic acid which is a weak acid.

A car drives through dirt and debris while rain just comes out of ocean >(which is what's happening now with these atmospheric rivers).
And snow is pure white where I live, at least until people walk near it.
I can see the FIRST rain being dirty like the roads get slick from oil,
but after weeks of almost daily rain, I wonder how much acid is left.
Didn't the EPA get rid of "acid rain" long ago in the US already?
For me, there isn't an industrial city anywhere and if there were, I guess >only a portion (How much? I don't know) of the acid is washed out in each >rain. And, only a portion of the acid is ADDED to the atmosphere each day.
Of course, then the ratio matters, for example, if we have ten rains, and
10% is washed out in each rain, the next rain is clean; however, if 5% more >is added between each rain, then it would take 20 rains to wash it all out, >and even then, 5% would be added the very next dry day.
So if you had two dry days in a row, it would take another rain to wash it >out. But didn't the EPA fix all that long ago?
If you ever run into a statistic on how acid the rain in the rural areas of >the US alongside the ocean is, that would be interesting information.
In article <news:nPEuL.278444$iS99.199685@fx16.iad>, Scott Lurndal ><scott@slp53.sl.home> says...
And, a warmer atmosphere holds more moisture, so there will be even more
lower-pH rain.
Warm(er) water holds LESS dissolved gases than cold(er) water.
Not more.
But you're correct that the warmer atmosphere may hold more water
although tell that to the Gobi Desert so it's not just the temperature.
Overall it's a wash I'll bet that the amount of dissolved CO2 is the same
now as it was before the media learned to change the terms every few years >from global warming to climate change and more recently to climate crisis.

In my part of Virginia rain runs about 5.9 pH. 7.0 is neutral. Anything above 7 is alkaline and anything below is acid.
So yes, our rain is acid. In an iron or battery I suspect the problem is more dissolved minerals than acidity though. I would be careful about cleanliness in the collection vessel. A rain barrel is likely to have all sorts of chemical and biological

Only thing there that I would use it for would be batteries and the iron.

Not around here. Around here, the rainwater leaves VERY obvious spotting. >Layer thick enough that you can see color in it too.

Depends where you are. In Tidewater, VA you can see a big triangle of >increased corrosion downwind of the trash-burning plant.
