Course Goals:  Chemical analysis methods are used to determine chemical, physical and/or structural properties of a substance. Methods used to provide the identity of a substance or structural information, are called qualitative chemical analysis methods. Methods that determine the amount of a substance are called quantitative chemical analysis methods. In this course, we will be primarily concerned with these quantitative methods as well as techniques used to separate components of a mixture.  We will look at the underlying chemical principles and phenomena upon which these methods are based. Quantitative analysis is generally the first course students see in the field of analytical chemistry...one of the five main areas of chemistry.

 

University Level Competencies: Winthrop University's faculty have adopted a set of four University Level Competencies (ULCs) that describe the qualities our students develop during their studies at Winthrop. It's easy to see that this course involves solving problems and developing good communication skills.  However, you will also learn about the responsibilities of chemists to the greater good of our planet and society, as well as the global nature of chemistry.  Within our discussions of chemical analysis, applied to the environment, health and materials we use every day, I think you will find this course fits well with all four competencies.
 

Competency 1: Winthrop graduates think critically and solve problems. Winthrop University graduates reason logically, evaluate and use evidence, and solve problems. They seek out and assess relevant information from multiple viewpoints to form well-reasoned conclusions. Winthrop graduates consider the full context and consequences of their decisions and continually reexamine their own critical thinking process, including the strengths and weaknesses of their arguments.

You will be using sophisticated mathematical and descriptive methods to solve problems found in environmental, pharmaceutical, biomedical, energy, food, forensic and electronic fields, for example.

 

Competency 2: Winthrop graduates are personally and socially responsible. Winthrop University graduates value integrity, perceive moral dimensions and achieve excellence. They take seriously the perspectives of others, practice ethical reasoning, and reflect on experiences. Winthrop graduates have a sense of responsibility to the broader community and contribute to the greater good.

Chemistry touches 95% of everything we use, daily.  Chemists need to be critically aware of industry impacts on the environment and human health.

 

Competency 3: Winthrop graduates understand the interconnected nature of the world and the time in which they live. Winthrop University graduates comprehend the historical, social, and global contexts of their disciplines and their lives. They also recognize how their chosen area of study is inextricably linked to other fields. Winthrop graduates collaborate with members of diverse academic, professional, and cultural communities as informed and engaged citizens.

Chemistry is a global enterprise with many industries located around the world that impact our quality of life.  Chemistry is a core topic, touching most fields of interest from science, to art, to technology.

 

Competency 4: Winthrop graduates communicate effectively. Winthrop University graduates communicate in a manner appropriate to the subject, occasion, and audience. They create texts including but not limited to written, oral, and visual presentations that convey content effectively. Mindful of their voice and the impact of their communication, Winthrop graduates successfully express and exchange ideas.

 

Science, in general, is difficult to understand, so correct, clear and effective communication methods are key.  Peer review is fundamental to scientific communications.

 

Student Learning Outcomes: By the end of this course, you should be able to:

 

Course Prerequisites: Grades of C or better in CHEM 301 (Organic Chemistry I), MATH 201 (Calculus I), and PHYS 211 or 201 (Physics I) are required before attempting this course. You are expected to have a firm grasp on the principles introduced in these courses. We move at a brisk pace and will not have the time to review concepts from these courses.

 

Course Co-requisites: You should also be registered for CHEM 312 (Introductory Chemometrics) and CHEM 314 (Quantitative Analysis Lab).

 

Attendance: You are expected to attend each class meeting for the scheduled time. This will help you to concentrate on the appropriate material and reinforce the assigned readings and problems.

 

Course Requirements: You must bring pencil, paper and scientific calculator to each class. Cell phone calculators are not acceptable. You may find your textbook helpful.  Be sure you know how to do mean, standard deviation, logarithms (base 10 & base e, including inverses), as well as least squares (i.e. - linear slope & intercept) with your calculatorYou are required to complete: 1) four in-class exams, 2) thirteen homework assignmewnts and 3) a standardized, cumulative final exam as indicated on the lecture schedule. For your convenience and calendar, dates for the in-class exams and final exam are:

 

February 1 (Exam I - Ch. 0,1,6,8)

 

March 5 (Exam II - Ch. 23,24, 25)

 

March 28 (Exam III - Ch. 18,19, 21)
April 16 (Exam IV - Ch. 14,15)

 

Thursday, April 25 11:30 am (Final Exam - Cumulative/Standardized)

 

Official Textbook: Harris, D.C.; Lucy, C.A  Quantitative Chemical Analysis, 10th edition, Macmillan Learning, New York. 2020. Other analytical chemistry textbooks are available in the library and are helpful as additional practice.

 

Homework Assignments: Quantitative Analysis is a course that focuses primarily on numerical problem solving.  To be successful, this often requires a substantial amount of practice.  Homework problems have been assigned for each chapter through Achieve to help you master the skills.  Recommended additional problems from the textbook are also listed on the Homework tab.

 In-class Exams: Each in-class exam consists of an in-class portion (multiple choice questions and open-ended problems) and a take-home Excel problem that is due with the in-class portion.  You need a calculator for each in-class exam and may NOT share. Formula sheets, tables, and scratch paper will be provided. You're expected to show all work to receive full credit. Lack of, or incorrect units is an automatic one-point deduction. The take-home Excel problem (no collaboration allowed) must have proper format features and formula documentation to receive credit. Our textbook has numerous spreadsheets showing how to properly document a spreadsheet.

Final Exam:  The final exam is a cumulative, standardized exam produced by the American Chemical Society.  It consists of 50 multiple choice questions.  Formula sheets, tables and scratch paper will be provided.  Each answer is worth 2.5 points, so scoring above 100 is possible. 

Grading: To determine your letter grade, the average of your four in-class exam scores will contribute 50% to your course grade total. The average of your homework assignments will contribute 30% and the final exam will contribute 20%. Letter grades will then be assigned from the sum as follows: 94-100%: A; 90-93%: A-; 86-89%: B+; 82-85%: B; 78-81%: B-; 74-77%: C+; 70-73%: C; 66-69%: C-; 62-65%: D+; 58-61%: D; 55-57%: D-
