AP Chem - did a few more volumetric analysis problems, showing that titrations are often used to assay the quantity or concentration of a given substance or ion in a solution.
We began to walk through the all-important "HALF-REACTION METHOD" of redox (or any equation) balancing.
Your stoichiometry tests were returned. Well done to those who heeded my advice, which has not changed ever since our first meeting last spring before you signed up for this very challenging course.
It really should not take an epic failure for you to follow such advice; however, every year, I do see students who initially balk at any kind helpful suggestions, and then who abjectly fail, yet eventually progress tremendously, and make a significant transformation, once they treat this class with the gravity and attention that it demands. One of the ultimate long-term benefits of this course for those who successfully complete it is their development and expansion of so many essential academic skills, their exploitation of their full academic potential, and their growth in emotional toughness.

7/8 finished up the catalase lab by seeing the effect of increasing acid concentration (lowering pH) on the catalase enzyme activity.
