2018 saw some of the highest AP Chemistry scores in years. The College Board released each test question covering topics from enthalpy to net ionic equations, as well as scoring guidelines and more to benefit future scientists. Example...

More than 83,000 scholars earned college credit, thus saving time and money by passing the AP Chemistry exam in 2017. Use the exact test questions covering concepts from activation energy to solubility to prepare for the upcoming...

More than half of AP Chemistry test takers earn a high enough score to get college credit. Improve that statistic by using past test questions including precipitate, molarity, and chemical equations to prepare for a future exam. The...

The College Board published the mean score on the 2016 AP Chemistry exam as a 2.69, but a minimum of a three is required to earn college credit. Help pupils study for the upcoming exam with actual test questions, sample answers, and...

More than 80,000 scholars earned college credit for Chemistry with the AP exam in 2015. The College Board released the free-response questions covering topics, including moles, that often confuse scholars. They also released example...

In this experiment, you will concentrate on understanding the chemistry of ion exchange and estimate the capacity of an ion exchange column from your observations.

In this experiment, you will study the reaction between your cobalt complex and the nitrite ion. The nitrite ion can exchange with a water ligand and the mechanism of this ligand exchange will be investigated. Requires Java plug-in.

In this experiment, you will examine the acidity of your coordination complex's water ligand. You will determine the acid dissociation constant of the complex by titrating it with a base. There are eight weeks of experiments in this series.

In this experiment, you will explore the behavior of the monoprotic acid (acetic acid) and the polyprotic acid (phosphoric acid). By titrating, you will examine the acid and conjugate base species present across the pH scale and the...

In this experiment, you will determine the rate law and confirm the mechanism of the reaction between cyclohexanone and iodine. Requires Java and QuickTime plug-ins to access some features.

This lab further analyzes the results of the experiments carried out in Chemical Kinetics 1. In addition, you will carry out experiments to determine the temperature dependence of the reaction rate constant. Requires Java plug-in.

In the first part of this lab, you will measure the absorption spectra of two conjugated dyes and compare the results to the theoretical predictions of a particle-in-a-box model. In the second part of the experiment, you will identify...
