Chem 1B with a C or better (C- not accepted).
Quantitative Chemical Analysis; 6 th ed. By Daniel Harris, – required – available
in Spartan Bookstore. Supplementary material at www.whfreeman.com/qca
Lab Manual: Quantitative Analysis Laboratory; S.P. Perone – required – available in the lab
or via SAACS, DH 504, during business hours the first two weeks of the
semester.
Lab Notebook: An acceptable laboratory notebook, with carbon copy pages, will be
required for all students. Notebook carbons will be due at the conclusion of
each day of lab. All primary data must be taken in the notebook in ink. In
many industry or research situations, the lab notebook can be used as a legal
document, so good notebook habits are essential for success in science!
Notebooks can be purchased in Spartan or Robert’s bookstore on 10 th street. It
is fine with me if you use part of an old notebook or one in use for another
class.
Exercises: In this course we will: a. discuss quantitative chemical analysis, statistics and
error analysis, chemical equilibria, acid-base and buffer chemistry, basic
spectrophotometry and chromatography b. conduct lab experiments in
acid/base and EDTA titrimetry, flame and solution photometry, electrochemistry
and high performance liquid chromatography.
Content:
Exams:
The lecture will cover material from chapters, the latter time permitting:
0,1,2, 3, 4, 6, 7, 8, 10, 11, 12, 14, 15, 18, 21, 22, 23, 24, 25. The pace and
timing of the lecture, including suggested homework problems will be
determined during the semester. Anticipate about 1 week per chapter.

Grading:
A single letter grade will be assigned for CHEM 55. The lecture and the
laboratory portions of the course carry roughly equal weights. A passing grade
in CHEM 55 requires a passing grade in both the lecture and the laboratory
portions of the course.

ADDENDUM TO ALL CHEMISTRY DEPARTMENT GREENSHEETS
(Except Chem 291 Sections)
Revised August 2002
CHEMICAL SAFETY – all courses
Chem 120S is a required course for all chemistry majors and minors and a prerequisite for all
Chem 180/298 research.
EMERGENCIES AND EVACUATIONS – all courses
If you hear a continuously sounding alarm, or are told to evacuate by Emergency Coordinators
(colored badge identification), walk quickly to the nearest stairway (end of each hall). Take
your personal belongings, as you may not be allowed to immediately return. Follow
instructions of Emergency Coordinators. Be quiet so you can hear. Once outside, move
away from the building. Do no return to the building unless the Police or Emergency
Coordinators announce that you may.
DISABLED STUDENTS – all courses
Any student with a pre-existing disability requiring an accommodation (as documented by the
Disability Resource Center) should make this need known to the instructor during the first two
weeks of classes. Every effort will be made to accommodate your needs.
ACADEMIC DISHONESTY – all courses
Academic dishonesty of any sort will subject the involved person(s) to university mandated
consequences. You should be familiar with the section of the SJSU Catalog entitled “Policy of
Academic Dishonesty” (pp.448-449 in the 2002/04 Catalog). Incidents of academic
dishonesty may be referred to the Chief Judicial Affairs Officer of the University and reports
may be placed in Department and /or University files.
For courses with written assignments include:
Note in particular that plagiarism, word-for-word copy of another person’s words without proper
attribution (quotation marks and a clear literature reference), is a particularly serious form of
academic dishonesty.
LABORATORY SAFETY – all laboratory courses
You should read the safety section of the SJSU Catalog under Chemistry Department (page
136 of current 2002/04 Catalog). Note in particular: “Failure to comply with proper procedures
and prescribed safety cautions shall subject the student to disciplinary action. 1) Any student
who engages in unauthorized experimentation, or who seriously disregards safety, thereby
endangering self or others shall be withdrawn immediately from the class with a grade of F. 2)
Any student who show persistent disregard for safety may have his/her grade lowered, and
may risk being withdrawn with a final grade of F.”
