CHM141 ANALYTICAL CHEMISTRY

Instructor: Gregor Kos

E-mail: gkos@ubishops.ca

Office: J-219

Office Hours: Monday to Thursday; open door policy or email me for an appointment.

Class room: J-322

Class Time: Monday and Wednesday, 10h00–11h30

Textbook: G.D. Christian; Analytical Chemistry, Sixth Edition,

John Wiley & Sons, Inc., Toronto, 2004. Chapters 1-11.

Assessment: Two assignments and two midterm exams will be given during the term.

Together with the final exam they will determine the final mark:

Assignments 10%

Midterm 1 (in-class): 25%

Midterm 2 (in-class): 25%

Final: (scheduled) 40% or 65% whichever gives the better overall mark

i.e., in the latter case, the midterm with the lower mark will not be counted.

No supplemental exams for the midterms will be scheduled. The sole criterion for a supplemen-

tal final exam is for a student who fails the course but gains the right to sit a supplemental exam by

achieving a course grade of 35% or higher. Passing the supplemental exam will result in a course grade

of 50%. Assignments handed in after the posted deadline will receive a 20% deduction of the final

mark. Please see me before the deadline or (for medical reasons only) after with a doctor’s note for an

extension without deductions.

Attendance:

Attendance is optional. The onus is on the student to meet the demands of the course and I sug-

gest strongly that regular attendance be the norm. To be excused from the midterm (no supplemental)

or final examination (deferred/supplemental exam as per university regulations), a student must present

a doctor’s note or other official excuse.

CHM141 ANALYTICAL CHEMISTRY

Course Content

Chemistry CHM141 is an introduction to the theories and concepts of analytical chemistry. The

course will closely follow selected topics from Chapters 1–11 of the assigned textbook. Chapters 2 (lab

operations) and 5 (stoichiometry) are revisions and, therefore, assigned reading for all students.

Chapter 1: Analytical Objectives, or What Analytical Chemists Do

(Chapter 2: Basic Tools and Operations in Analytical Chemistry)

Chapter 3: Data Handling in Analytical Chemistry

Chapter 4: Good Laboratory Practice: Quality Assurance of Analytical Measurements

(Chapter 5: Stoichiometric Calculations: The Workhorse of the Analyst)

Chapter 6: General Concepts of Chemical Equilibrium

Chapter 7: Acid-Base Equilibria

Chapter 8: Acid-Base Titrations

Chapter 9: Complexometric Reactions and Titrations

Chapter 10: Gravimetric Analysis and Precipitation Equilibria

Chapter 11: Precipitation Reactions and Titrations
