IntoTheNight, a very simple question for you

[ThatOwlWoman]

thanks. that family (actually the missus) was overly obsessed with any sort of impurities real or imagined.

I still find it surprising that water (just plain old H2O) is acidic. I would have bet money that it was as neutral a thing as there could be.

Live and learn.

The water molecule's two hydrogen atoms give it that acidity.

Not really. The acidity comes from other things like CO2 in the air which the water absorbs.

H2O + CO2 -->HCO3- + H+

The H+ that is liberated from this rxn is what gives water its acidity. There may be other aspects related to the salts that get dissolved, etc. But the acidity from water isn't just because it has two hydrogens. Water by itself, all things being equal, should have a neutral pH (7). It is not uncommon for water to be of lower pH because of the effect of CO2 absorption (dropping down to pH 5-6).

Mind if I ask what was funny about my response? (Hopefully I didn't make any serious error?)

so it does. around here water was always described as being as harmless a thing as there was.

Instead it's called the "universal solvent."

Water - Both an Acid and a Base

I think apple cider vinegar took that role at least down south where its used for everything not food related.

No errors. Basic freshman chemistry. You made owl look pretty foolish. I thought that was funny.

Which doesn't change my original point. In fact your link actually says exactly what I said about CO2.

Water is not an acid.

Water does not absorb CO2. CO2 can be dissolved in water, but water does not absorb it. Dissolved CO2 is not an acid.
Discard of acid-base chemistry.

Define "acid". Define "water".

invalid chemical formula. CO2 dissolves in water. That is not an acid.

Water is not harmless.

Instead it's called the "universal solvent."

It is often referred to as such, since most anything will either dissolve in water or be eroded away by water.

Water - Both an Acid and a Base

Water is neither acid nor alkaline. And acid is not an alkaline. Redefinition fallacies.

Actually, it wasn't. The chemical formula he gave is invalid. CO2 simply dissolves in water. Only a very small part of it becomes carbonic acid. Think soda pop and you'll get the idea.
