Introduction and Philosophy
Episode 1 of Chemistry, 2nd Edition
In this first lecture, Professor Cardulla explains how any student can find success in chemistry by cultivating a meaningful understanding of the concepts and quantitative thinking operations that underlie this often challenging area of study.
Basic Concepts of Quantitative Reasoning
Episode 2 of Chemistry, 2nd Edition
Introductory chemistry is not mysterious: It requires simple quantitative reasoning that comes naturally to most students. You learn about the types of numbers involved in chemistry and how to solve problems commonly encountered in high school chemistry.
The Mole
Episode 10 of Chemistry, 2nd Edition
One of the most important concepts to master in an introductory chemistry course is the concept of the mole, which provides chemists with a way to "count" atoms and molecules. Learn how scientists use the mole and explore the quantitative…
Quantitative Reasoning in Chemistry—Density
Episode 4 of Chemistry, 2nd Edition
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…
Ions, Compounds, and Interpreting Formulas
Episode 8 of Chemistry, 2nd Edition
Learn about protons, electrons, and neutrons; how ions are formed from atoms; how these ions can combine to form compounds; and how you can determine the formulas of these compounds. Some molecular substances are discussed and you are introduced to…
Elements, Atoms, and the Periodic Table
Episode 7 of Chemistry, 2nd Edition
In the next three lectures, you cover some fundamental topics that you'll need before you can launch into your study of chemistry. You examine the basic building blocks of matter--elements and the atoms that constitute them--and you learn how to…
The SI (Metric) System of Measurement
Episode 5 of Chemistry, 2nd Edition
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…
Quantitative Reasoning in Everyday Life
Episode 3 of Chemistry, 2nd Edition
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…
An Introduction to Molarity
Episode 19 of Chemistry, 2nd Edition
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,…
Solving Mole Problems
Episode 11 of Chemistry, 2nd Edition
By solving problems involving moles, you refine the quantitative techniques introduced in earlier lectures while increasing your familiarity with this important chemical value.
Converting between Systems of Measurement
Episode 6 of Chemistry, 2nd Edition
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.
Basic Concepts of Chemical Equilibrium
Episode 22 of Chemistry, 2nd Edition
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."
Solving Molarity Problems
Episode 20 of Chemistry, 2nd Edition
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.
Writing and Balancing Chemical Equations
Episode 15 of Chemistry, 2nd Edition
What happens when you combine two or more elements? Through a variety of practice problems, you learn to identify when a chemical reaction has occurred, how to write chemical equations, and how to "balance" equations to conserve the atoms.
Strong Acids and Bases—General Properties
Episode 29 of Chemistry, 2nd Edition
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.
Isotopes and Families of Elements
Episode 9 of Chemistry, 2nd Edition
Discover how isotopes, which are different atoms of the same element, can actually differ in their weight because they contain different numbers of neutrons in their nuclei. Also, learn how different kinds of elements are grouped into both general categories…
Advanced Molarity Problems
Episode 21 of Chemistry, 2nd Edition
You are asked to take the concepts you learned about molarity in the last two lectures and apply them to a number of unfamiliar problems. These problems offer an opportunity to test your comprehension of the concepts you've been exploring.
An Introduction to Stoichiometry
Episode 16 of Chemistry, 2nd Edition
What are the quantitative relationships between the substances in a chemical reaction? The study of stoichiometry shows you how to apply your ability to balance equations to solve problems involving chemical reactions.
The Self-Ionization of Water
Episode 28 of Chemistry, 2nd Edition
After examining how different substances may behave when dissolved in water, you learn about the self-ionization of water and use this knowledge to solve problems. The lecture ends with a brief introduction to the pH of solutions.
Titration Curves and Indicators
Episode 33 of Chemistry, 2nd Edition
Acid-base indicators, which change color when a solution switches from acid to base and back again, provide a striking demonstration of the transformation that occurs during titration. Learn how to use these indicators to determine the equivalence point of a…
