General Objective:

This course intends to introduce the bases of analytical chemistry for chemistry and biochemistry majors. The emphasis is put either on understanding the theoretical aspects of quantitative analysis or problem solving skills.

LEARNING GOALS:

Students should:

• Know the physical bases for analytical methods discussed during the course and understand them

• Be aware of the sources of errors and have knowledge how to avoid them

• Know how to calculate the amount of analyte in the specific application of each method

• Know how to obtain calibration curve and how to use it for an analytical purpose

• Know the criteria, which are used for choosing the methods for a particular analysis.

CONCEPTUAL THINKING OBJECTIVES:

• Reading: cause-effect logic, hypothesis testing, summarizing logic

• Writing: cause-effect links, objective designing, experiment planning

• Data analysis: relevant data sources, data treatment, qualitative and quantitative evaluation, data consistency, error analysis

• Models: cause-effect, correlation, trends

LEARNING ACTIVITIES:

• Text reading

• Class‐time (lecture)

• Hand on experience (laboratory)

• Group discussion

• Computer‐aid instruction

• Problem solving (individual)

• Student‐instructor consulting

Assessment tools:

The final grade is calculated as follows:

Best three scores of the four in-class examinations (35%)

Quizzes (5%)

Final Exam (35%)

Laboratory (25%)

* The lowest grade exam will be dropped. Missing an exam will result in receiving a zero grade for that particular exam and thus dropping that grade. There will not be any Make-up Exams.

Office Hours:

Mondays: 8:00 am – 9:00 am

Mondays: 12:30 pm – 1:30 pm

Wednesdays: 12:30 pm – 1:30 pm

Or by appointment

Office is located in the science building in room MR 1224

Absence Policy (Attendance)

Students are expected to attend every class session of each course in which they are enrolled and to be on time. An instructor has the right to drop a student from a course for excessive absence. Students are advised to determine the instructor’s policy at the first class session. They should note that an instructor may treat lateness as equivalent to absence. (No distinction is made between excused and unexcused absences.) Each instructor retains the right to establish his or her own policy, but students should be guided by the following general College policy: In courses designated as clinical, performance, laboratory or field work courses, the limit on absences is established by the individual instructor. For all other courses, the number of hours absent may not exceed twice the number of contact hours the course meets per week. When a student is dropped for excessive absence, the Registrar will enter the grade of WU.

Statement on Academic Integrity

The CCNY policy on academic integrity will be followed in this course. The document can be found through the CCNY website by clicking on Current Students ( Academic Services ( Policy on Academic Integrity. All students must read the details regarding plagiarism and cheating in order to be familiar with the rules of the college. Cases where academic integrity is compromised will be prosecuted according to these rules. In addition, the Policy of Academic Integrity can be found in the Undergraduate Bulletin 2007-2009 in Appendix B.3 on page 312.

Disability

In compliance with CCNY policy and equal access laws, appropriate academic accommodations are offered for students with disabilities. Students must first register with The AccessAbility Center for reasonable academic accommodations. The AccessAbility Center is located in the North Academic Center, Rm. 1/218.  Tel: (212) 650-5913. Under The Americans with Disability Act, an individual with a disability is a person who has a physical or mental impairment that substantially limits one or more major life activities. If you have any such issues, I encourage you to visit the AccessAbility Center to determine which services may be appropriate for you.

Courtesy

Noise and excessive chatter, eating, drinking, or use of unauthorized electronic equipment is not allowed in the classroom.

Make-up examination for INC grades

INC may be assigned to students who have a passing grade (average on all the exams) in the course but who are unable to take the final examination due to conflict with another scheduled examination, death of spouse, injury sustained in a catastrophic incident, etc. (proof is also required). An Incomplete Grade Agreement form must be signed by the Instructor before the student is allowed to take the makeup exam. Payment of a fee at the Bursar's office is required in order to take the makeup examination. Makeup exam for INC grades in Chemistry courses will be completed no later than two weeks after the end of classes.

Final Examination will be scheduled during the final exam period. Our Tentative exam date is on Wednesday, May 21st, 2014. The time of the exam is 10:30 am – 12:45 pm.

Study Guides:

1. Plan at least three hours of study (reading the chapter and completing the problem sets -“homework”) time for every hour you spend in class.

2. Do the problem sets individually (without help from friends or classmates) initially. Please look at a related problem in the solution manual to help you solve the assigned problem. If you are still unable to solve the problem, then ask a friend, classmate, workshop leader, TA, or Professor for help.

3. Read the book and take notes as you read.

4. Seek help when you have difficulty (office hours, tutoring, study groups).

“I hear, I forget. I see, I remember. I do, I understand.”
