Second Semester Chemistry covers the topics found in the second half of a normal high school chemistry textbook. It’s the continuation course following First Semester Chemistry.
You’ll see and perform a variety of laboratory activities to reinforce the concepts hands-on. Most of the advanced math, technical jargon, complicated chemicals, and fancy lab equipment have been removed from the topics so you can truly master the chemistry concepts.
We’ll spend about half the course understanding acid-base-water chemistry conceptually, in addition to making pH predictions. You’ll learn how the whole world is in equilibrium, why matter flows, the conditions under which chemical reactions occur (or not), how to generate electricity, and the relation of all these concepts to this invisible stuff called energy.
Videos Included: The video textbook has 250 videos (35 hours total) including complete chemistry lessons, detailed worksheet solutions, 25+ experiments, and instructions for reporting laboratory data.
Materials Included: The course has 45 printable pdf files including worksheets, answer keys, and class notes.
Time commitment: Learners typically spend 3-7 hours per week, which includes combined live in-class time and out-of-class time.
Course duration: Semester length (half school year) or summer session.
Instructor Support Included: Dr. Scott teaches the live class personally. He is available for questions and evaluates worksheets by email. There are grades and a certificate of completion at the end.
Learners completing Second Semester Chemistry will be able to:
We learn about pH and dilutions.
We learn about dilutions factors, ICE tables, and percent dissociation for acids.
We learn about strong and weak acids and tabulated pKa tables.
We learn about strong and weak bases as proton acceptors (Broenstead-Lowry bases). We learn about salts being either neutral or basic.
We learn about conjugate acid and conjugate bases that exist as conjugate pairs. We focus on writing proton acceptor and proton donor reactions. We discuss pKb and pOH for bases, much like pKa and pH for acids.
We learn about titration curves, plotting the pH as an acid-base reaction proceeds past the endpoint of titration.
We learn about making buffer calculations and preparing buffers. We learn about shifting equilibria and the Le Chatelier principle
We shift topics to learn about the equilibrium that exists between a liquid and the vapor over it’s surface, an extremely common situation on Earth. We learn to read steam tables and vapor pressure data.
We learn about pressure conceptually and scientifically.
We do an all time classic experiment to collect gas over water, correcting for the vapor pressure of water. We calculate the Gas Constant R from experimental data from a simple kitchen setup.
We learn more about the gas laws, the Joule-Thompson cooling effect, and the design of internal combustion engines using PV diagrams.
We consider thermal degradation with oxygen (combustion) and without oxygen (pyrolysis). We discus the products, including charcoal, or pure carbon. We perform an experiment to use activated carbon as a filtration medium to separate contamination from water.
We do the iodine clock reaction, a true dazzler in the world of chemistry. We’ll do a simple and safe kitchen version, and we’ll get introduced to rates and chemical kinetics.
We will see the theoretical connection between equilibrium and rates for chemical kinetics. It’s a major, over-arching theory that connects many of the big ideas in chemistry. We’ll make reaction diagrams showing the activation energy and enthalpy or heat of reaction.
We get an introduction to electrochemistry, and we build a battery (voltaic cell) using a fruit or vegetable such as a potato.
Second Semester Chemistry follows First Semester Chemistry in the chemistry course series.
After completing this course, you’ll be ready for more of our advanced chemistry courses including our unique, high school level, multi-part Organic Chemistry courses.
Hi, I’m Dr. Scott, the course instructor and author of the digital textbook that you get with the course.
I’m a a former college chemistry professor that knows how to make learning science fun and easy. I spent waaay too many years watching students fail “hard” college science courses because they didn’t get the fundamentals.
My courses will show you how to learn science, and I guarantee they’ll prepare you for future science classes. The easy way.
