I haven’t really read much Science Daily, tbqh…

But yes… “Scecece” can I get an introduction? I think we just might be able to be best friends!

I just find it funny because of how Science Daily has really been stooping to insane sensationalization for their articles. Thanks for the information, though!

There’s also a really weird comment attached to this post, and I’m trying to determine if it’s random spam or not. It isn’t advertising anything… I might just added it and see. :)

Edit: There we go, first comment. It makes no sense!

The reason that most colas are some-what acidic is because of the phosphoric acid they have in them.

However, I wouldn’t fret too much. Most of the food products we consume are acidic, and most cleaning products are basic. And water is anaphoric, meaning it can act as either an acid or a base. And battery acid is sulfuric acid, which has a pH of about 0. So soft drinks aren’t too close to that pH. And it also kind of depends on the molarity(M) of the solution (cola). I mean… if its only 1M phosphoric acid, you aren ‘t going to get nearly as much too erosion as you would if you were to have say, a 6M phosphoric acid solution.

Anyways… I’ll stop babbling. My point is, it doesn’t necessarily depend on the concentration of hydronium ions. There are much more factors to consider.

And if you’re interested, here are some formulas to help you calculate pH and pOH blah blah blah:

1.0×10^14 = [H3O+][OH-]
[H3O+] = 10^-pH
pH = -log([H3O+])
pOH = -log([OH-])

And as a final note, I <3 Coke.
