Concept Review Sheet: Exam 2 (not guaranteed to be exhaustive)
Exam 1 ended with charge- and mass-balance, and systematic treatment of equilibrium, so exam
2 will begin with material covered immediately after that. However, earlier concepts (such as
Review Sheet of HPLC Concepts for Final Exam (not necessarily complete)
HPLC = high performance liquid chromatography not high pressure liquid chromatography
HPLC is typically used for separating the ~95% of all compounds that are not sufficiently volatil
The acid dissociation equation:!
HA + H2O
H3O + A
If HA is a weak acid, its conjugate base is also weak.!

Steps to approaching analysis:
- Choose what's to be analyzed
o The rest is called the Matrix
- Get a representative sample
o Sample is either homogenous/uniform (preferred) or heterogeneous
- Prep the sample
