Monday: Reviewed pH concepts from Friday’s homework, then did a chemActivity to learn the difference between Arrhenius and Bronsted-Lowery bases and definitions of conjugate acid/base. At the end we did a quick exploratory lab where you didn’t write anything down in a lab notebook.  We measured the pH and concductivity of HCl, HC2H3O2 and water and compared the results.  I asked, “Why is the pH for acetic acid always lower than HCl even though they are the same concentration? Doesn’t pH depend on concentration?”  The answer led to a discussion of the difference between solubility and dissociation.  SMART  BOARD NOTES

Tuesday: We did a chemactivity to learn the difference between strong and weak acids.  I gave a list of strong acids and bases you need to know as well as went over organic acids and bases.  We also did problems where an acid reacts with a conjugate base of another acid and you learned how to figure out whether the forward or reverse reaction was stronger using a table of relative acid strength.    SMART  BOARD NOTES

Wednesday: Today we started with these questions.  When going over those we defined polyprotic acids, monprotic and diprotic acids and showed how conjugate bases of diprotic acids can be amphoteric (act as both an acid and a base).  The second half of class we did Ka and Kb calculations to determine pH w/ this worksheet.
