Course Description: Welcome to Analytical Chemistry (CHEM 3310), a 2- semester credit class that will introduce the major aspects of quantitative chemical analysis. This Analytical Chemistry course is appropriate for students who are majoring in the natural sciences, science education, engineering, and pre professional programs. This course assumes that an adequate degree of 1

2 collegiate level knowledge has been achieved (and retained) from a two semester General Chemistry sequence since many of the concepts discussed in this class build directly upon the material learned in freshman level chemistry such as stoichiometry, equilibrium, acid base reactions, and electrochemistry. This course will study in detail the analytical process including the techniques and methods used to isolate and quantify specific analytes in samples of materials. Major topics that will be discussed in this course include sample preparation, equilibrium, titrations (e.g. acid base, precipitation, complexation, and redox), electrochemistry, spectrophotometry, and separations. This course will focus on the quantitative procedures of measurement using chemical and instrumental methods in order to compare analysis to theoretical information obtained from equilibrium and stoichiometry using statistical methods. Required Text: Quantitative Chemical Analysis by Daniel C. Harris ISBN- 13: Edition Number: 8 th Pub. Date: April 2010 Publisher: Freeman, W. H. & Company Online Materials: Sapling Learning All Homework Assignments and Quizzes are to be completed through the Sapling Learning website. An access key must be purchased from Sapling Learning for access to this website. Blackboard - This system is maintained by The University of Toledo and is utilized to post items such as PowerPoint presentations, handouts, lecture outlines, notes, and announcements so that they may be accessed online. The WebCT site can be accessed at using your UTAD user name and password as your access code. Companion Website for required text - Homework, Quizzes and Examinations: Homework Eight (8) mandatory and graded homework assignments can be accessed through the Sapling Learning website. These eight homework assignments will be assigned over the course of the semester. The due dates and availability for these assignments will be announced in class. Homework assignments account for 40% of the final course grade. Quizzes Five (5) Quizzes will be given throughout the semester through the Sapling Learning website. Each quiz will be worth 20 points. Quizzes will be available for a short period to be announced in class and must be completed within a certain specified time limit. All quizzes account for approximately 10% of the final course grade. Examinations Exams, which account for 50% of the final course grade, will be in large part modeled after homework and quiz problems, as well as material and examples presented in 2

3 class. There will be a total of 3 midterm exams and one comprehensive final exam. Each midterm exam will be based on course material presented since the previous examination through the lecture prior to the exam date. Exam dates are as follows: Exam #1 Wednesday September 12 th Exam #2 Wednesday October 10 th Exam #3 Wednesday November 14 th Final Exam as scheduled during Finals week All exam solutions must be written in blue or black ink pen (no pencil). Make- ups exams will not be given for any circumstance. Excused absences will be given only to students who miss an exam under the conditions listed below. If an excuse is acceptable, your final course grade will be computed based on all work except that exam. For all exams please bring your university photo identification card and your non- programmable calculator. You will not be permitted to use a programmable calculator or have a cell phone or any other electronic device on your desk. Exam Absence Policies Students who will not be able to take an exam at the scheduled time due to an irresolvable conflict with a major responsibility must provide some written documentation to verify the conflict. This situation may occur for students on official university business, including athletes. The exam will be given at another arranged time. Approval must be obtained before the scheduled test date. Students who do not take an exam due to illness, car accident or similar extreme circumstance should inform their instructor of their difficulties as soon as possible. These difficulties must also be documented by physician's notes, accident reports, etc. A telephone call to either the instructor or the Chemistry Office ( ) within 24 hours of the exam is expected. Students must complete an Absence Report Form in all cases of missed examinations. These can be obtained from the General Chemistry Secretary in the Chemistry Office, BO2022. Documentation supporting your excuse must be attached to the form. In all other circumstances a missed exam will result in a grade of 0. Regrade Policy: Quizzes and Exams are typically graded by teaching assistants using a detailed rubric provided by the instructor. Any request for regrade must be submitted to the instructor within one week of the return of the graded quiz/exam and the posting of solutions. Absolutely no regrading will be done after this one week period. Note that even if there is issue with only one question or component of the quiz/exam, a request for regrade may result in the entire quiz/exam being reassessed by the instructor, which may result in an overall lower quiz/exam score. 3

4 Drop, Withdrawal, Instructor Withdrawal and Incomplete Grades: Course drop and withdrawal procedures have been set by the University faculty. Dropped courses do not appear on your transcript. If you are in a course after that date, there will be a grade on your transcript. You may withdraw from the course and receive a grade of W. The deadline for withdrawal is usually the half- way point of the semester. W s do not affect your GPA. For both procedures you should go to the Registrar's Office in Rocket Hall. You do not need your instructor s permission for either process. Please note that course registration changes might change your financial aid. The IW grade is given only to students who have not been in regular attendance in this course. The IW grade is not given as a late W grade for students who are attending and participating in the course. It is the student s responsibility to withdraw from the course if that is the best option. If you complete one or more quizzes or exams you are not eligible for an IW. A course grade of Incomplete is given only to those who have completed all but a small percentage of course requirements for an acceptable reason. The Incomplete must be removed before you take courses like Instrumental Analysis for which this course is a prerequisite. Grades and Grading Policies: In this course there will be absolutely no curving of scores. Curving places students in competition with each other for grades. The scale that we use is a guarantee, i.e., if you earn 90% or more of all the points you WILL receive a grade of A. The scale given below is not a 90/80/70/60 etc, but is more realistic for college science courses. At any point in the course you can calculate how many points you need to achieve a certain letter grade. You will want to check your grades on a regular basis (errors and misunderstandings are possible) but learning and understanding analytical chemistry is the goal, so don t get overly focused on points. Note that the comprehensive final exam that is worth 20% of your grade allows you to end strong and improve your grade. Be sure to ask about any grade uncertainty. The following is a break down of the possible points in this course: Quizzes (online) points (total) Home Work Assignments (online) points (total) Practice Problem Sets (online) - No course credit 3 Midterm Exams points (100 points each) Comprehensive Final Exam points Total points 4

5 The grading scale for exams is as follows: % = A % = A % = B % = B % = B % = C % = C % = C % = D % = D % = D+ < 50% = F Academic Dishonesty: You are urged to refer to the university's policy on Academic Dishonesty found on p. 25 of the university catalogue. Violation of this policy can result in a course grade of F. Remember that only nonprogrammable calculators are allowed during quizzes and exams. There are to be absolutely no cellphones, smartphones, ipod Touches, netbooks, tablet PCs, computers, and books allowed out or on your desks during quizzes and exams. Communication: You are urged to communicate with the instructor about any aspect of the course which concerns you or which might limit your success. We want you to be successful in this course, so let s work together! is a great way to communicate, so send a message at any time. Honors Students: All Honors students will be assigned an additional project, whose successful completion will be required to receive Honors credit. A meeting will be scheduled with all enrolled Honors students during the first quarter of the semester to outline and discuss this project. A deadline for completion of this project will also be specified. Attendance/Absences: If you have a valid excused absence (see university webpages for policy on what constituted a valid excuse) you will be allowed to make- up any graded portion of the course missed. Excused absences have 24 hours to contact the instructor or Chemistry Department Main Office by or phone. Documentation must be provided at the earliest convenience.
