Becky,
our tried and true lab-rat assistant, came to the rescue once again. During the morning Bio-Tech
class the solution of Hydrogen Peroxide was tipped over and half of the
solution spilled out. The student,
not wanting to get into trouble, filled the container with water making
the
solution a watered down Hydrogen Peroxide. The
next class complained that the Hydrogen Peroxide
solution was 50% of
what it should be. Becky quickly
took 1/3 of the solution out and added twice the strength of the
original
Hydrogen Peroxide solution. Did her
idea work? Good Luck!!!!!
