Episode 35 of Chemistry, 2nd Edition Course

Your study of solubility equilibria continues with some advanced practice problems. Here, you encounter the last major type of equilibrium problem. To solve these problems, you revisit Le Chatelier's Principle and learn about some of the pitfalls to avoid when dealing with these kinds of equilibrium systems.

Solubility Equilibria—Principles, Problems

After learning about equilibrium systems, you move on to a particular type of system: "solubility equlibria," or the equilibria found in saturated solutions of slightly soluble ionic solids. You explore this concept as you practice solving a variety of related problems.

Le Chatelier's Principle—Concentration

Before you can solve equilibrium problems, you need to understand what happens to an equilibrium system when conditions are changed. You learn about a fundamental idea--Le Chatelier's Principle--which lays the groundwork for a broader understanding of equilibrium.

An Introduction to Equilibrium Problems

You use your basic understanding of equilibrium systems to try to solve some problems. You tackle two kinds of equilibrium problems: ones in which you are asked to calculate the equilibrium constant for an equation, and ones in which you are asked to find the equilibrium concentration of a reactant…

Chemistry, 2nd Edition Course

Many students struggle in high school chemistry. Even if they succeed in earning a good grade, they often still feel confused and unconfident. Why is this? And what can be done to help every student succeed in this vitally important course? Success in chemistry, according to veteran science teacher Professor…

An Introduction to the Equilibrium Constant

By tracking and graphing a hypothetical reaction as it approaches a state of equilibrium, you gain a deeper understanding of the essential characteristics of equilibrium systems. Then, you're introduced to the single most important expression used to solve equilibrium problems: the equilibrium constant.

Le Chatelier—Pressure and Temperature

Having established a basic understanding of Le Chatelier's Principle, you explore how this principle plays out in a variety of situations in which an equilibrium system is changed.

Strong Acids and Bases—General Properties

You return to the topic of pH and learn about how pH relates to two kinds of compounds: acids and bases. Through an introductory problem, you explore the relationship of various ions within these compounds.

Interpreting an Equilibrium Constant

Your examination of the equilibrium constant continues. Learn exactly what the numerical value for an equilibrium constant tells and doesn't tell you about an equilibrium system.

Putting It All Together

In this final lecture, you tackle problems that require you to pull together all the knowledge you've acquired. Through these challenging problems, you build confidence in your ability to unravel new problems and pursue more advanced levels of chemistry.

Solving Molarity Problems

Extend your understanding of molarity by solving some typical problems encountered in the high school chemistry classroom. To foster your understanding of these problems, you are asked to draw upon the quantitative reasoning skills you previously used.

Quantitative Reasoning in Everyday Life

Only a handful of important ideas must be mastered in order to be successful at solving chemistry problems. In this lecture, you review some basic guidelines for approaching any chemistry problem and try out your skills on a few sample problems that demonstrate how you can use everyday reasoning in…

Advanced Stoichiometry

As you move on to more advanced stoichiometry problems, you see that they can be solved using a very simple approach. You encounter three terms often applied to chemical reactions: theoretical yields, actual yields, and percent yields.
