Strange buffer properties

When the buffer gets dilute enough, the autoionization of water takes
over, since neutral water contains about 0.0000001M hydrogen ions and
the same concentration of hydroxide. So under completely clean
conditions, if you continue to dilute the buffer, the pH will begin to
drift toward 7. In real life, the CO2 in the air and crap from the
sides of the containers will probably dominate the pH instead.

Why not try the experiment?
