Just the other day, I was cleaning out the chemical cabinet and came across some 7.0 pH
buffering solution for calibrating a pH meter. Since my meter has long since bit the dust
and new batteries did not rejuvenate it and it was beyond the 1 year warranty, well, I
threw it away.
If anyone has interest in this solution, respond by week end else it too may end up down
the drain.
