QUANTITATIVE ANALYSIS
Old (1998) Exam #1 Answers
- #1. The Butler did NOT do
it!
- #2.
- a.) FALSE. Alpha-functions are for acids. Bo is the mole ratio
of the uncomplexed metal ion ([M2+]/CM).
- b.) TRUE. As ionic strength increases, the
activity coefficient decreases, resulting in increased solubility
(increased concentration of salt ions in solution).
- c.) FALSE. This is a random (indeterminate)
error and has an equal probability of being a + or - deviation.
- #3. 6. x 10-12 mg/L
- #4.
- a.) 1. x 10-6 mg Ag2S/L
- b.) Solubility Decreases
- #5. 23.8 mL AgNO3 Solution
- #6. Yes! Quantitative removal of Ba2+ is
possible
