AP: tomorrow, we have the second in our trilogy of acid-base equilibria exam: this exam encompasses the skills from the first exam (of course) and then expands to the following subtopics: explanation of relative acid strengths based on bond polarity and bond strength- make sure that you can DRAW the Lewis structure for any acid molecule and relate that structure specifically to source(s) of bond polarity and bond strength and how each affects acidity ; acidic/basic/neutral salts based on hydrolysis of water (be able to write equations thereof);bronsted acid-base and Lewis acid-base theory: meaning and applications; the meaning, application and relationships of Ka and Kb expressions and values; acid-base equilibria calculations using acids, bases, or salts; calculations involving buffers of a specific pH- the Henderson-Hasselbalch equations; calculations involving the addition of strong acid or base to a buffer solution or to a weak acid or base solution.
I was very impressed with the class performance on the last exam; I sense that you can make it two in a row; study hard!
