Chemblog!

Considering all of the exams this year, the next two exams are the most challenging. You must know ALL of the material from the last acid base exam and subsequent material up to and including common-ion calculations for sparingly soluble salts (from today). There is no AP exam hw question tonight; just CONTINUE to study for the test by doing as many practice problems of every kind that you can find among the worksheets/notes/ text.
One of the keys to success on this test (as you noticed on the last test) is RECOGNIZING the problem type! Is it a buffer problem? a titration? a salt of a conjugate acid or base problem? The only way to know what you are doing is to get experience with each problem type and recognize the differences among them.
