acid rain and carbon cycle?

How does acid rain affect the carbon cycle?
i dont need too much details, just a sentence or two. thanks 🙂

I would mention instability if carbonic acid or even hydrogencarbonate.

Remember the acids other than Carbonic ( e.g. Sulphuric ) that can make rain acid. Action is different.
When they talk about acid rain, then, especially historically, it’s good to remember that they might not have been talking only about carbonic.

well, H2CO3 doesn’t contribute to acid rains, so it’s kind of irrelevant 😉 I was going for something else.

Jackbean, do you mean that acid rain reacts with limestone to form carbonic acid, which decomposes into H2O and CO2?
November 8, 2011 at 7:34 am #107822
not really lime, the rain is not that acidic, but stones and plants are not the only carbon storages

What do you mean "doesn’t contribute" ?

What is wrong with this from wiki? One might like to go into detail wrt to issues over "alkalinity", "basicity", perhaps, but wrt to carbonic acid being "irrelevant", I don’t get it.quote :

distilled water does have pH 7 without removing anything, since distilled water should be pure, w/o any CO2 🙂
Anyway, CO2 is not the main acidifying factor. At least, if we speak about industrial pollution

There is a world of difference between "should be" and "is", Jack 😀
The CO2 in the condensation tube goes right back into the water. Often the pH of distilled water is below 6.
Wiki can hardly be faulted for mentioning it that way.
As well, if distilled water is pure, then why does industry or lab sometimes demand "double distilled" ?

no, pH of freshly distilled water is pretty close to 7, but if you let it stand for some time, it will drop, because it absorbs some CO2 from air.
Anyway, CO2 is not the main cause of acid rains.
