How pure is rain water ?

Answer 1

Its not very clean as such but my dog prefers rain water to tap water.

Answer 2

The firstly obtained rain water may be acidic. But in a continuous rain the later amount may be assumed as 99.9999% pure. Generally no trace element is found.

Answer 3

Sadly all of the rain has acid in it.
If you live in or to the west of any major pulluting cities then the rain will have a large amount of acid in it.
EX. The adirondack Mountains in New York State are getting ruined because of all of the pollution that factories are creating in Chicago.

Also when the water runs off of land that is dirty (mud, etc.) and evaporates back into the air it brings up some of the dirt that it picked up with it.

Answer 4

Each DROP of rainwater is made up of 10,000 tiny Droplets, each of which form around a tiny dust particle in the atmosphere. So each drop of rainwater could hold 10,000+ dust particles. Work out for yourself if it is "pure" or not. if you think its hard to believe, look at your car after a shower. Why, we've even had the Sahara desert brought over to the UK in the rain!
incidentally thats why we have clouds, because clouds are massive amounts of water droplets each formed around a minute dust particle. only when tiny droplets join in vast numbers to make a rainDROP do the clouds give off rain.

Answer 5

it all depends on where you are, if you are in a picture perfect place with no harmful chemicals in the atmosphere, then there is less of it getting into the rain... because for the most part this is not the case, rainwater is always slightly acidic with a pH of slightly less than 7.

rainwater in theory should be very pure because of the way in which it is distilled naturally, it is evaporated, then condensed once more into water.

Answer 6

As pure as the air it fell from.
Acid rain occurs in the area downwind of sources of sulphur dioxide. Generally it's almost as good as distilled water.

Answer 7

Rain is inherentley impure as it condenses onto dust and impurities in the air, hence cloud seeding where rain is caused artificially by dropping powdered chemicals into clouds to make them rain prematurely.

Answer 8

not as pure as it should be or uses to be
because of air polution
they found polution in Antarctica and the noth pole
that came there in high moving layers of air that surround the globe

so today dont drink the rainwater espescially near the cities

the best water still is from very high mountain streams or from springs or holes in a mountain

Answer 9

Its not that pure, in towns anyway as It contains all the impurities from the earth carried up into the air as water vapour

Answer 10

very soft water, but only as pure as the stuff that got it out
of the sky in the first place, the water it came from, and
whatever it fell through coming down (and the mud puddle
you dipped it out of)
