Learners view an animated presentation showing how the pH level of a cleaning solution is controlled in a closed-loop system in a manufacturing setting. A quiz completes the activity.

Learners follow a four-step process to determine the empirical formula of a compound from the masses of its constituent elements. The molecular formula is determined in a fifth step using the molecular weight of the compound.

Learners complete an exercise to match chemical formulas with the names of binary compounds, tertiary compounds, and ions.

Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.

In this interactive object, learners examine how to properly dilute hydrochloric acid.

Learners examine the meaning of theoretical yield, actual yield, and percent yield. They test their knowledge by solving two problems.

Learners view movie clips to determine the solubility of two ionic compounds. They also examine a solubility chart and predict the solubility of compounds.

Equilibrium plays a vital role in our lives. We'll show you how the equilibrium formula works in real life using our friend the chicken.

In this animated object, learners view hydrogen and hydroxide ions in a solution. A brief quiz on the basic principles of the term pH completes the activity.

In this interactive object, students examine a type of chemical bond known as the "hydrogen bond."
