The acidity of urine isn't very important in terms of corrosion. An
understanding of chemistry would lead you to conclude there simply
isn't enough acidic strength in urine to make it an effective caustic.
On the other hand, the salts are reactive, and become more so as the
water matrix evaporates. As mentioned before, cars parted where salt
water spray wets them are all of the demonstration of that an
intellegent disinterested observer might need.

Stong's Physical Chemistry text -- it's a pretty old book, but good --
will even allow you to put numbers to the analysis. It's, oh, more or
less junior year college stuff -- can you handle that?

The normal pH is very close to 7 (neutral).

Your provider may want to modify your urine pH to help prevent kidney
stones. Acidic urine is associated with xanthine, cystine, uric acid, and
calcium oxalate stones. Alkaline urine is associated with calcium carbonate,
calcium phosphate, and magnesium phosphate stones.Acid, alkaline. See?

The normal values range from 4.6 to 8.0.And the average is just about 7.0.
