All Mixed Up




            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!!!!!
