UF CHM 2046: General Chemistry 2
CHM 2046 is UF's second general chemistry course, covering kinetics, equilibrium, acids and bases, thermodynamics, and electrochemistry. Huge cohorts of pre-health, science, and engineering students take it with the CHM 2046L lab, and it continues the gen-chem sequence that gates organic chemistry and the pre-med track.

What makes it hard
Equilibrium is the conceptual wall: ICE tables, Le Chatelier reasoning, and the cascade from Ksp into acid-base and buffer problems all build on each other, so a shaky equilibrium foundation collapses the back half of the course. The exams stay timed multiple choice with no partial credit, so the multi-step equilibrium calculations are exactly where careful setups quietly lose to arithmetic slips.
What you'll cover
- • Chemical kinetics and rate laws
- • Chemical equilibrium and ICE tables
- • Acids, bases, and buffers
- • Solubility equilibria (Ksp)
- • Thermodynamics: entropy and free energy
- • Electrochemistry
The CHM 2046 study guide
How to study for UF CHM 2046, step by step.
- 1
Master equilibrium before everything else
Acid-base, buffers, and solubility all extend the same equilibrium reasoning in CHM 2046. Get ICE tables and Le Chatelier automatic early or the whole second half wobbles.
- 2
Drill multi-step problems under time
Timed multiple choice with no partial credit means one slip in a five-step equilibrium problem costs the whole question. Practice the full chains on a clock.
- 3
Build a buffer-and-titration playbook
These are the densest problem types and the highest-yield exam points. Work enough of them that the Henderson-Hasselbalch decisions become reflexive.
- 4
Connect thermo and electrochem to free energy
Entropy, free energy, and cell potential are linked relationships, not separate facts. Learn the connections so the late-semester units reuse what you already know.

FAQ
Is CHM 2046 harder than CHM 2045 at UF?
Many students say yes. Equilibrium is conceptually deeper than the stoichiometry-heavy first course, and the back half (acids, buffers, solubility) all builds on it. A weak equilibrium foundation makes everything after it harder, so master it early.
What's the hardest topic in CHM 2046?
Equilibrium and its extensions: ICE tables flowing into acid-base, buffer, and solubility problems. The reasoning is cumulative, so students who don't lock it down in the equilibrium unit struggle through the rest of the semester.
Do I need CHM 2046 for pre-med at UF?
Yes. CHM 2045 and 2046 with labs are the standard general chemistry foundation, and they're prerequisites for organic chemistry. The material also appears on the MCAT, so genuine understanding here pays off well beyond the course grade.

CHM 2045: General Chemistry 1
CHM 2045 is UF's first general chemistry course, covering stoichiometry, atomic structure, bonding, thermochemistry, and gases. Huge cohorts of pre-health, science, and engineering students take it alongside the CHM 2045L lab, and it's one of the most consequential GPA courses for UF's large pre-med population.
CHM 2210: Organic Chemistry 1
CHM 2210 is UF's first organic chemistry course, covering structure, bonding, stereochemistry, and the reaction mechanisms of substitution and elimination. Pre-med and science majors take it after the general chemistry sequence. It's one of the most consequential courses on the pre-health track and runs in large lecture sections.
