Chemistry II with Aaron

Below are materials for SI Leader Aaron’s Chemistry II, instructed by Keubler, section 2, Spring 2017.



Exam 3 is on Monday, April 3. Check the section labeled Exam for the study guide. If it helped, consider coming to SI! The times are listed below at “SI Times and Locations.”

Exam 3 Review session:

  • CB2-105
  • March 31
  • 4PM-6PM
  • This exam review will be in the form of a Q&A session. No lecture is planned. All CHM2046 students are welcome and encouraged to come with questions.
    • No questions is off limits, with one rule: I will not explain homework/practice questions unless the due date is past, AND the answer is available.
      • I do this so that we can focus on HOW we get the answer, instead of what the answer is.

Similarly to Exam 2, ONLY the UCF ID is accepted!


Hello! My name is Aaron and I will be your Supplemental Instruction (SI) Leader for Chemistry Fundamentals II. This is my second semester doing SI for Chemistry II, and my fourth semester at UCF. I am a Physics major and I like cooking and spending time with my cat. I am excited for this new semester, especially for the unit on electrochemistry where we discuss one of the ways we generate electricity to power electronics!

About SI, Why should I attend SI?

Supplemental Instruction (SI) is a session that focuses on helping the student gain the skills they need to succeed in class. The central principle of SI is the “how” and “why” of lecture material, rather than the “what.” In SARC SI, someone who has taken a class and earned an “A” in the class guides students towards a solution to any problem or question they have.

Attending SARC SI gets results. Students that attend SI earn up to a full letter grade above their peers that don’t attend SI. My sessions in particular are geared towards CHM2046, especially because I attend the lectures in addition to conducting SI Sessions.

SI Logistics

SI Sessions are free. There is no registration, only sign-in for attendance. Try to arrive early, so you can see all the content in the session.

There is no lesson plan for SI. SI is based on the attendee, and as such, attendees determine the content in SI. It is not mandatory to come to SI with questions, some students come to practice their skills in Chemistry. Each session starts fresh!

Come prepared. Bring your textbook, notes and calculator. This is so that you can practice Chemistry skills and study skills without being inhibited by a lack of materials.

My SI sessions in particular will be very interactive. Be ready for group activities, games, practice problems, and group discussions. Prizes may or may not be involved.

It is never too late to start coming to SI! SI is for everyone. It can always help you get ahead of the competition.

Study Tips

  1. Stay healthy. Get as much sleep as you need. Eat fruits and vegetables and drink water. Don’t be afraid to miss a social event — doing well in class is important.
  2. Study in advance, every day. This varies from person to person, so find the pace that suits you best. The overall idea is to keep up with the material.
  3. Take notes! This works especially well for people like myself, that learn by doing.
  4. Do the practice problems. Do not simply Google a solution. Practice problems are there to help you sharpen your skills. It benefits you to not use a search engine because it is unavailable during exams. Doing well in practice problems correlates to doing well on exams.
  5. Come to SI! SI is not a relecture or a separate curriculum. It is more similar to a group study session. Collaborating with other students and asking me questions is a great way to study!
    • Note: Students that attended SI on a weekly basis scored much higher than students that did not attend SI at all (no numbers because of confidentiality policy).
  6. Dr. Kuebler’s office hours are another great resource. He will also guide you to finding the solutions to your questions.

How to Contact Me

The best way to contact me is in person: before Lecture, before SI, and after SI. I will be at the front of the lecture hall, with a gold UCF badge. I am not able to talk after Lecture; I have my own classes immediately after the Lecture so I have to run.


Exam 3 is on Acids and Bases + Ionic Equiliibrium.

Some popular exam questions:

  • What is the pOH of a solution with an amount of added weak acid?
    • What is the [H] given pOH?
  • Identify these as acids or bases, according to the Arrhenius/Bronsted/Lewis theory.
  • Which of these in this reaction is the conjugate base?
  • Rank these bases from weakest to strongest.
  • Dissolving this salt yields a(n) _______ solution (acidic or basic).
  • What is the pH of this buffer solution?
    • What is the pH of this solution, then, after I add more of the conjugate?
  • What is the pH at the half equivalence point of a titration?
  • What concentration of titrant is needed if X mL is needed to titrate a solution to its equivalence point?
  • How much of this salt will dissociate in solution given Ksp?
    • How can the conditions be changed so that more/less of it will dissociate?
