Analytical Chemistry I
Objectives:
General Information Winter 2005
CHEM*2400/2480
The purpose of this course is to provide a sound physical understanding of the
principles of analytical chemistry and to demonstrate their applications in
chemistry, biology, medicine, and the study of the environment.

Laboratory Manual:
The laboratory manual for CHEM*2400/2480 may be purchased
from SC2110 in the New Science Complex building at the start of the
semester.
Spreadsheets:
Spreadsheet problems can be completed using Excel, Quattro Pro or any
other spreadsheet program that you are comfortable using.
Lectures
Lectures will be presented in MACK 120 on Monday, Wednesday and Friday from 8.30 to 9.20
am. It is assumed that you are familiar with all material covered in CHEM*104/105 and it may
be necessary for you to review your first year notes in order to follow the lectures. Suggested
background reading is given at the start of any new topic.
At least two demonstrations of spreadsheet usage will be integrated with the lectures.
Students are responsible for any material covered in lectures and all suggested topics from the
text.
Consultation
The lecturer will be available for help and consultation in his office, SC 3114. Available times
will be announced in the first class.
Problem Sets and Spreadsheets
There are nine problem sets that can be downloaded during the semester. These assignments are
based on the lectures given and are to be attempted on your own. The main objective of most of
these problems should not be to obtain numerical answers alone, but to build and expand your
concepts of the course material. In other words, understand the chemistry. Spreadsheet problems
will also be posted on the web.
Answers to the problem sets and spreadsheets (Quattro Pro and Excel) will be posted on the web.
For personal help with the problem sets and spreadsheets, please ensure that you bring all
attempts that you have made of any problem.
Tests and Examinations
There will be one midterm test of two hour duration and a final examination of two hours.
Missed labs or a test or examination will carry a grade of zero. A valid excuse on medical or
compassionate grounds will be considered. Students may be asked to provide certification of
illness.
All tests and examinations must be written in ink. Midterm papers may be submitted for regrading within one week of the return of the graded papers. The instructor may refuse to re-grade
a paper, at his/her discretion.

The final exam will be on April 20, 2005 as assigned by the Registrar’s office.

The laboratory grade will consist of 70% for results on unknowns, 20% for the laboratory
notebook, and 10% for technique.
Students must pass the lecture and laboratory parts of the course independently to obtain
credit for the course. Otherwise a mark of 47% or the percentage mark calculated from the
above distribution, whichever is lower will be the reported grade.

Laboratory
Labs will be conducted in rooms 3103 and 3104. The ‘Balance’ room is 3102B. All rooms are
located in the new Science Complex
The 2480 section consists of one 3 hour lab per week. The 2400 have two 3 hour labs per week.
Experiments are of the Quantitative type. Using different procedures, the value for a standard is
first determined. An ‘unknown’ sample is then analysed by comparison with the standard. The
value for that specific sample is calculated using the data obtained from the experiment. The
techniques developed from these labs will equip the students to analyse most inorganic
compounds using classical and not so classical methods of analyses.
The laboratory section of the CHEM*2400/2480 course is very demanding and requires careful
organization to complete it successfully. You can only work in your assigned lab period.
Read the laboratory manual before you attempt any experiment. You must make a written plan
of what you will be doing in the laboratory. Before the start of each lab, you will be required to
show the Instructor this plan. The Instructor has the right to refuse a student access to the
laboratory if no such action has been implemented. The Instructor also has the right to hold
lab quizzes if he/she thinks fit.
On the first page of the laboratory manual there is a list of experiments to be completed. Cross
off the experiments as you complete them.
Also attached to your laboratory manual is a laboratory guideline. It is based on what an average
student would accomplish each week. Go through the guideline, make a list of things to do
(good for a few weeks) e.g. (l) prepare HCl solution (2) prepare NaOH solution (3) etc. - - and cross off each completed task. This will conserve laboratory time.
Do not be overly concerned if you are a week behind schedule. Any more than a week, you are
probably doing something incorrectly. Check with your laboratory Instructor immediately.
All safety procedures as outlined in the laboratory manual and those mentioned by your lab
Instructor will be strictly enforced. Chemical waste must only be placed into specially labelled
containers. Mixing certain chemicals could result in injury. Read the labels on the containers
before disposing any waste chemicals.
Students must obtain and use their own safety goggles and lab coats. Lab coats and safety
goggles are mandatory in the laboratory.
Failure to follow/obey any safety rules will be cause for immediate dismissal from the laboratory
