Help students prepare for the AP® Chemistry Exam. Select these integrated, interactive activities to help students review principles and concepts
for major areas on the AP Chemistry Exam. Choose from the following five products, containing three separate demonstrations per kit. Students
observe and record data, perform calculations and analyze the results to answer AP-style essay questions. Kits include all consumable chemicals
and equipment needed to perform all three demonstrations for two complete class sections.
Acids and Bases
By: The Flinn Staff
Listed for acids and bases by the College Board are the concepts of Arrhenius,
Brønsted–Lowry and Lewis, coordination complexes, amphoterism, pKa and pH,
buffers and hydrolysis. Use this set of three acid–base demonstrations to both
engage students in a hands-on review and test their understanding.
• Weak Base–Weak Acid Titration—Start the review with a titration of a weak acid
with a weak base. What is the pH at the endpoint? Students graph pH versus
volume of base added. Based on the graph and their knowledge of endpoint pH
calculations, students determine the relative strengths of the acid and the base.
• Acid Mixture, Concentration and Ka—A mixture of hydrochloric acid and maleic
acid is titrated with sodium hydroxide. Students graph the titration curve and use
the data to determine the concentration of each acid in the mixture and the Ka of
maleic acid.
• Acid Strength and Electron-Withdrawing Groups—Show the trend for Ka of acetic
acid and its mono- and tri-chloride substitutions. Students explain this trend based
on these values and their knowledge of electron affinity.

Electrochemistry
By: The Flinn Staff
The course description for the College Board AP® Chemistry lists the following topics
for electrochemistry: electrolytic and galvanic cells, Faraday’s law, standard half-cell
potentials, Nernst equation and prediction of the direction of redox reactions. Use the
following three demonstrations host a lively and informative review of this core topic.
• The Voltaic Cell—Use standard electrode potentials and the Nernst equation to
predict the direction of current flow and the voltage when electrolyte concentrations
are varied.
• Electrolysis—Measure the change in pH for the electrolysis of potassium iodide
solution, and use Faraday’s law to determine the average current flow.
• Concentration Cell—Voltage produced with different concentrations of ions forges
a deeper understanding of the Nernst equation.

Stoichiometry
By: The Flinn Staff
The course description for the College Board AP® Chemistry lists the following topics
for stoichiometry: net ionic equations, balancing equations and mass and volume
relationships relating to the mole concept, empirical formulas and limiting reactants.
Use this set of three acid–base heat of neutralization demonstrations to both engage
students in a hands-on review and test their understanding of this sometimes difficult
Thermodynamics
By: The Flinn Staff
Use this set of three thermodynamics demonstrations to both engage your students
in a hands-on review and to test their understanding of this sometimes difficult yet
fundamental topic.
• Entropy and Free Energy—Exothermic crystallization of sodium acetate trihydrate
sparks a lively debate on spontaneity, free energy, enthalphy and entropy.
• Hess’s Law—Two-part calorimetry demonstration provides data for reviewing the
properties of state functions and performing H°, ΔS° and ΔG° calculations.
• Free Energy and Redox Reactions—Solve the Nernst equation for a copper concentration
cell to demonstrate the relationship between free energy and electrode
potential.

yet fundamental topic.
• Acid–Base Neutralization of Acetic Acid—Start the review with mono-protic acetic
acid. Use the method of continuous variations to mix the reactants. Students then
graph the change in temperature versus the volume of acid to determine the mole
ratio of two reactants.
• Di-Protic Acid Neutralization—Once students are comfortable with the continuous
variations method, switch to equal molar volumes of sodium hydroxide and the
di-protic weak acid, oxalic acid.
• Neutralization of Poly-protic Citric Acid—The mentioned stoichiometry topics all
come together in this final demonstration.

Oxidation–Reduction
By: The Flinn Staff
Use this set of integrated, interactive demonstrations to help students review the
major principles of oxidation–reduction. Set of two demonstrations includes:
• Reactions of Iron(II) and Iron(III) Ions—Investigate electron transfer reactions of
Fe2+ and Fe3+ ions with a series of oxidizing and reducing agents, respectively.
Students identify trends in the reduction of iron(III) ions as they review essential
knowledge and skills, such as how to assign oxidation states and balance halfreactions
for the AP® Chemistry Exam.
• Colorful Oxidation States of Manganese—Demonstrate the wide range of colorful
oxidation states of manganese, a continuous series from +7 to +2! Students
observe and compare the sequence of projected colors arising from oxidation of
manganese in its +2 form and corresponding reduction of its highest, +7 oxidation
state. Excellent review of balancing redox equations!
Includes valuable Teacher Notes with helpful teaching tips, reproducible student
worksheets and enough materials to perform each demonstration twice.
