I normally allow the poster the courtesy of replying, but as a long-
time tutor of AP Chemistry students, and a 30+ year student of
chemistry myself, I couldn't let the blatant misinformation that Jack
wrote go on to confuse people. Also, while the book I quoted is a
souvenir of my first college-level chemistry for chemists course,
that particular portion of the CRC hasn't changed in a long time (I
also have a 32nd edition antique ;-)

Ummm, unless you took chemistry somewhere *really* interesting, for
the most purposes, pH refers to a calculation involving the negative
logarithm of the hydrogen ion in solution. pH has a range of 0-14,
and outside the range of pH [4.0 < pH < 9.2], some correction factors
must be applied to the general equation.  pH 0 is extremely acidic,
pH 14 is as basic as you can get. {Reference Chemical Rubber Company
Handbook of Chemistry and Physics, 55th edition, 1974, p D-112)

Under normal circumstances, a pH of less than 7 is acidic, greater
than 7 is basic, and 7.0 is considered neutral.

They do have it right.

I did. Did you? You might want to verify your information next time,
using a known good source (*not* "I read it on the Internet, so it
must be true"), and quote the source of your information. If you are
going to make a really _silly_ boo-boo, at least blame it on someone
else :-)  :-0  :-)
