AP Chemistry Labs
Up until May 2006, laboratory situations were specifically tested in question #5 on the AP exam,
could also come up in parts of other free-response questions, and appeared in a few multiple-
choice items. In the new exam format for 2007 you should expect a laboratory based situation as
part of either question #2, #3, #5 or #6. Remember, question #2 and #3 are the ones where you
have a calculator (i.e. would probably involve calculations), but question #5 and #6 would most
likely not involve a calculation, and would probably be more like the pre-2007 question #5.
You should carefully note the following text taken from the College Board AP Chemistry course
“It is unlikely that every student will complete all of the 22 laboratory experiments below
while enrolled in an AP Chemistry course. Some of these experiments, in whole or in part,
may be performed during a student's first course in Chemistry before the student takes
the AP Chemistry course.”
It is worth bearing in mind that you have NOT be exposed to a “first course in chemistry” and, as
such, your lab experience is somewhat limited by your special circumstances (AP chemistry as
sophomores with only one year of chemistry).
Below is a table of the 22 “Recommended Experiments” as listed in the College Board AP
Chemistry course description. In addition to these specific lab situations, general techniques
relating to taking measurements, dilution, titration, tests for gases, conductivity, error analysis and
a myriad of other techniques are also potential questions, or part questions.
*In an attempt to keep the list of free-response examples manageable and relevant, I have
restricted the list to include only questions that;
have appeared SINCE 1990, AND
that actually make reference to a specific experiment/experimental situation or
Those questions that deal with ONLY experimental data, and then ask students to perform
to that experimental data, (as many Section A Free-Response
questions do), have deliberately NOT been included. This can be a fine line to determine.
