Quantitative Chemical Analysis, 4th Ed., Daniel C. Harris (Freeman)
Bound lab notebook with quadrille pages. Instructions to be distributed.
Safety glasses, long pants required; apron or coat recommended; no bare feet or sandals in lab.
Calculator with logarithmic and exponential (and hopefully statistical) functions.
HOUR EXAMS: (Subject to change by unanimous class decision):
October 01, Tuesday lab period
November 05, Tuesday lab period
December 11-15, TBA
Hour exams testing proficiency in general chemistry problem-solving will be given up to three times. The student's highest grade will be averaged in as a lab report grade. (Sept. 06, Oct. 11, Nov. 22).
Several quizzes covering reading, problems, lab and lecture discussions may be given at random, but will be announced one lecture in advance.
Will be assigned regularly, and will be reviewed during the recitation/quiz period. Feel free to consult instructor about any difficulties in solving problems.
Reports are due on the deadline indicated for each experiment (usually one week following the scheduled completion of the experiment). Reports turned in after the deadline will receive a late penalty of 10% plus one point per calendar day late.
Each student will develop a specific chemical analysis, according to his or her interests. During the semester, the student will research the literature to find available methods for executing this analysis, finally submitting a "position paper" comparing the methods. In consultation with the instructor, one method will be chosen and then carried out during four lab periods of the course. The project and results will then be described in a formal written report and brief oral report. Guidelines for this project will be distributed throughout the semester.
Exam and Quizzes 400 (3 exams, plus quizzes, scaled to 400 pts) Lab Experiments 400 (7 reports, 1 Stoich. Exam, scaled to 400 pts) Individual Projects 200 (Position Paper, Final Report, Oral Report, Lab Eval) Extra Credit 3 pts added for each Chem Colloquium attendedLetter grades will be assigned on the following basis: 100-90%=A; 89-88=A-; 87-86=B+; 85-80=B; 79-78=B-; 77-76=C+; 75-68=C; 67-66=C-; 65-63=D+; 62-58=D; 57-56=D-; <56=F
