General
Course Information
- Required Text: Elementary Chemical Analysis by C. Rushing
- Co-requisite: Chem 152
- Course Objective: By taking this course concurrently with General
Chemistry II, Chem 152, the student will gain laboratory experience and the
opportunity to verify or to invalidate concepts taught in lecture. By the
end of this course, students will be able to:
- identify an unknown using qualitative analysis
- determine the concentration of a base via titration with an acid
- determine pH using indicators, pHydrion paper, and a pH meter
- determine the concentration of a solution using a Spectronic 20 Colorimeter.
Course Grading Policy
- Attendance: Attendance at each laboratory is mandatory, as described
in the college catalog, p. 25. All lab work will be done independently, unless
otherwise stipulated. Failure to be present in lab due to guard duty, procurement
leave, honor court trials, etc. will result in a 0 on that day's quiz and
lab report.
- Make-up: There will be no make-up labs in this course.
- Honor in the Class: All students will adhere to the Citadel honor
code described in The Guidon, and as such will not cheat on any work submitted
to the instructor for a grade. Cheating will not be tolerated!
- Quizzes: There will be a total of four quizzes throughout the semester
(see lab schedule for dates). Each quiz will address the month long experiment:
the reading, associated calculations, and report. Quizzes will be given at
the begining of the lab period. All quizzes count for mid semester grades.
At the end of the semester, the lowest quiz will be dropped. The remaining
quizzes will be averaged for 67% of the course grade.
- Laboratory Reports: Lab reports, turn-in sheets, are due the next
lab meeting (see lab schedule for dates). All questions on lab reports are
to be answered independently of classmates. Late lab reports will not
be accepted for a grade. All reports count for mid semester grades.
At the end of the semester, the lowest report will be dropped. The remaining
reports will be averaged for 33% of the course grade.
- Final Exam: There is no final exam in this lab course.
- Midterm Grade: According to the percentages above and the scale below,
mid term grades will be calculated and assigned. All quizzes and reports to
date count towards midterm grades.
- Final Course Grade: At the end of the course, the lowest quiz and
report grades will be dropped and the remainder averaged. The quiz average
will constitue 67% of the course grade and lab reports 33%.
Scale for Final Course Grades:
- A: 100-90
- B: 89-80
- C: 79-70
- D: 69-60
- F: 59-0
Note
LD students: It is the responsibility of these students to provide the
professor with written documentation from Dr. Barbara Zaremba regarding their
special needs. According to Citadel policy, all letters addressing special needs
must be processed by Dr. Zaremba. Letters from Dr. Zaremba must be received by
this professor at least two days prior to the quiz and mutually acceptable
arrangements must be made by this same timeframe between the professor and the
student. All quizzes will be administered in the presence of this professor.

- To prevent food poisoning from chemicals in the lab, food, drink, tobacco,
smoking, and gum are all prohibited in the lab.
- To prevent eye loss, students must wear goggles at all times while working
in the chemistry lab. Any student caught working without adequate eye
protection will be required to wash their eyes at the eyewash station.
- Students will alert the lab professor of broken glassware, mercury spills,
and any accidents.
- Students will adhere to the safety precautions given for each experiment
to minimize risk.
- Any student endangering the life of a classmate or the professor will be
removed from the lab.
- To minimize exposure to chemicals, students will recap bottles following
usage and clean-up any spills.
- Excess and spilled chemicals should be added to the designated waste bottle
in the lab room.
- Glassware should not be dried with paper towels, as paper fragments will
be left behind.
- Broken glass should be placed in the cardboard box for glass.
- Extinguished matches should be placed under running water before putting
into crock.
- All borrowed equipment must be returned before leaving the lab.
- Gas jets must be turned off when not in use. Burners should not be left
