What to Expect from Study.com Chemistry 112L Class📖
So what will you face in the study.com Chemistry 112L: Chemistry II with Lab? Consider it as going a step higher than chemistry I; things are not so simple here but then again it is not bad at all. You will be getting into such interesting areas as kinetics of reactions, equilibrium constants, and electrode processes. If you have ever asked a question like ‘How do batteries function?’ or ‘Why do some reactions occur more quickly than others?’, then you’ll find the answers to these questions and many more in this course.
First, you revisit key areas from Chemistry I such as reaction rate, but this time you learn more not only the impact of temperature and concentration but also how it influences or is affected by the reaction rates. Then, you’ll move on to chemical equilibrium and learn how systems balance themselves out (spoiler alert: The shift in equilibrium in the reaction also has an effect on the concentrations of the reactants and products, it is a way of maintaining balance and this is where Le Chatelier’s Principle comes in. These two concepts will most certainly be played a lot, so make sure you get well-acquainted with them!
At the tail end, you can get into some pretty nifty areas like electrochemistry where you will discover things like oxidation-reduction reactions and see how it works in using batteries and even in preventing corrosion. Do not overlook organic chemistry and polymers, albeit these are the fundamental units that dominances life as well as numerous tests. You’ll also have to watch processes in biochemistry and know the structure and functions of the principal biomolecules such as carbohydrates, lipids, and proteins. Ironically, this class will make sure you’re on your toes literally all the time, but at least by the time of the proctored final, you will be confident enough!

Key Topics to Focus On 🔑
Some of the most important areas that you are likely to come across when going through the course are as follows. Understanding these concepts will make you get prepared and even confident when the big day comes. Here are four major areas you should deal with to help you sort things out a bit, I’ve included a few comparisons, some examples of real-life situations, and diagrams.
1. Chemical Kinetics vs. Chemical Equilibrium
|
Concept
|
Chemical Kinetics
|
Chemical Equilibrium
|
|---|---|---|
|
Definition
|
The study of reaction rates and how fast reactions occur.
|
The state where the forward and reverse reactions happen at the same rate.
|
|
Key Formula
|
Rate = k[A]^m[B]^n
|
Kc = [Products] / [Reactants]
|
|
Real-World Example
|
How fast food spoils at different temperatures.
|
Saturated sugar solution in water (equal dissolution and crystallization).
|
|
Important to Remember
|
Reaction rate is influenced by temperature, concentration, and catalysts.
|
The equilibrium position shifts based on Le Chatelier’s Principle.
|
2. Acid-Base Equilibrium
This is a very important point for the exam so make sure that you understand how acids and bases react to each other, particularly in cases of buffer solution and titration. Here’s a breakdown to clarify things:
Buffers: A buffer is a solution that retains its pH value when an amount of acid or base, solution is added to it. They play a central role in such functions as maintenance of blood pH.
- Formula: pH = pKa + log ([A-]/[HA])
- Example: The bicarbonate buffer system in the human body helps maintain blood pH around 7.4.
Titration Curves: Titration is a procedure that involves gradually adding a third variable called titrant to a solution so as to find the concentration. The equivalence point is defined as the state in which the volume of acid is equal to the volume of base.
- Strong Acid vs. Strong Base Titration: pH at the equivalence point is neutral (pH 7).
- Weak Acid vs. Strong Base Titration: pH at the equivalence point is greater than 7 (basic).
3. Redox Reactions & Electrochemistry
|
Term
|
Oxidation
|
Reduction
|
|---|---|---|
|
Definition
|
Loss of electrons.
|
Gain of electrons.
|
|
Mnemonic
|
OIL - Oxidation Is Loss
|
RIG - Reduction Is Gain
|
|
Real-World Example
|
Rusting of iron. Iron loses electrons to oxygen (oxidation).
|
Photosynthesis: plants reduce carbon dioxide into glucose.
|
|
Electrochemistry
|
Study of redox reactions where chemical energy is converted to electrical energy (and vice versa).
|
Use a standard reduction potential table to determine which reactions will happen in electrochemical cells.

Study.com Chemistry 112L FAQ❓
Q: How important is the lab component in this course?
A: The lab component is the most important one. This question is out of 300 and as we can assume it’s 100, it is very dangerous to miss it or not pay enough attention to it. The labs are also good in supporting the theoretical concepts that are taught in the lessons and are therefore important to grasp the knowledge.
Q: What should one do to prepare for the proctored final exam since it allows only a minimum of movement?
A: Make sure that students grasp the major ideas of each chapter. One way to begin could be to click through the quizzes on study.com and just practice with them until the time you are conversant with them. A clear understanding of the calculations and the formulas involved should be understood in chemical kinetics, simulation of equilibrium, and electrode processes. _do not forget to revise the periodic table and it is essential that you write down the various formulae and calculations to use while taking the test!
Q: Is this to mean that the quizzes are open-book?
A: You actually get 3 shots at all the quizzes and as much as none are proctored you should employ the quizzes as proper instruments of checks. Your best attempt of the first three attempts will count towards the final grade, therefore, use the first attempts well. The quizzes help one prepare well for the final exam because when you’re attempting the quizzes, you study well in order to know what you are doing.
Q: Can I retake the final exam if I don’t pass?
A: Yes! If you’re unsatisfied with your score, you can retake the proctored final exam after a 3-day waiting period. But remember, you can only retake it twice. Use that time to go over the study guides, rewatch videos, and revisit the chapters where you struggled.
Q: What should I bring to the final exam?
A: Make sure you have the allowed items:
- Blank scratch paper
- Pen or pencil
- Non-graphing scientific calculator
- Printable periodic table (you must print it; viewing it online during the exam is not allowed) These items will help you stay organized and focused during the test.
Q: How do I know what topics will be tested heavily?
A: Chapters covering chemical kinetics, equilibrium, acids and bases, electrochemistry, and organic chemistry are likely to feature heavily on the final exam. These are core topics in any Chemistry II course, and understanding them thoroughly will give you a big advantage.
