Episode 6 of Chemistry, 2nd Edition Course

Now that you have established an understanding of the SI system, put your knowledge to work as you practice converting units from one system of measurement to another. You hone your conversion skills by working several sample problems.

The SI (Metric) System of Measurement

Next, you continue to lay a strong foundation for your understanding of chemistry by learning about one of the key tools you'll be using: the International System of Units (SI), or the metric system. This lecture explains why this system is so useful to scientists and lays out the prefixes…

Quantitative Reasoning in Chemistry—Density

Building on the ideas explored in the first three lectures, you examine a fundamental quantitative measurement in chemistry, density, and explore the real-world meaning of this measurement. You then solidify your understanding of this concept by working some basic density problems.

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.

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…

Solubility Equilibria—Common Ion Effect

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.

An Introduction to Molarity

One important idea to master in any introductory chemistry course is the concept of concentration of a solution. Here, you explore this concept, the components that make up a solution, and learn about a basic unit of measurement for concentration, molarity.

Chemistry Tutor: Units and Unit Conversions

This program covers the important topic of units and unit conversions in chemistry. We begin by discussing the primary units that will be used throughout the course. Next, we illustrate a very powerful technique to convert from one unit to another that the student will use in virtually every chemistry…

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.

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.

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…

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.

Basic Concepts of Chemical Equilibrium

Continue your study of chemical reactions by examining an important new concept: the equilibrium system. You start by looking carefully at the difference between reactions that "go to completion" and those that are "reversible."
