CONTACT INFORMATION

COURSE POLICIES

• Make sure you sign in each day you come to class– Under no circumstances should a student sign in for

someone else

• If you are not in the right class, request a change (on-line in the duck)– Give me a feed back

COURSE POLICIES

• Attendance: – Attend and participate in every class meeting– Inform me via email if you cannot attend a class in a particular day– Habitual absentees may be penalized– Habitual tardiness will not be tolerated

• I am here to help you; contact me any time, any day; take good advantage of that; let’s build a healthy relationship

COURSE POLICIESJust coming to class is not enough

– Download, print and read course materials before coming to class– Pay attention to the instructor– Participate in class activities (try to answer questions, be involved in

class discussions)– Ask questions– Join group discussions– Read notes and other materials everyday and solve a lot of questions– Turn in every homework given you (submit on or before due dates)– Always be prepared for quizzes and exams– All the above are still not enough

• Notebook computers should not be opened unless authorized to do so

• Computers and/or cell phones cannot be used as a calculator for exams

• Cell phones must be completely turned off

COURSE POLICIES

• Academic Misconduct– Common forms: cheating, plagiarism– Academic dishonesty will result in a grade of zero for the

work involved and reported to the office of Student Life/Judicial affairs

• Disruptive behavior (abusive, threatening, profane) will not be tolerated

• No eating, drinking, or smoking in the classrooms

COURSE POLICIES

• Grades:

3 examinations at 100 each 300Term paper (including presentation) 100Homework 100Practical 100Final Exam (comprehensive) 200Total 800

Late assignments will be penalized (10% per day)Bonus quizzes may be given throughout the semester to help

students earn additional points

COURSE POLICIES

• Grades– Midterm grades reflect about 20% of total grade– Students may choose to withdraw– Withdrawal deadline is March 4, 2011– Must fill official withdrawal form (Registrar’s office)– No grades will be given out over phone or email– Complete student survey and course/instructor

evaluation at the end of semester

INTRODUCTION

What Is Chemistry?

- The central science (it merges into physics and biology)

- The study of matter and energy and the interactions between them

- The branch of the natural sciences concerned with the characteristics, composition, and transformations of matter.

- Everything we hear, smell, taste, see, and touch involves chemistry and chemicals (matter)

INTRODUCTION

Divisions

- Analytical (methods of analysis of matter)

- Physical (theory and concepts of chemical problems)

- Organic (compounds of carbon)

- Inorganic (compounds of elements other than carbon)

- Biochemistry (compounds of living matter)

INTRODUCTION

What Is Electrochemistry?

- Redox chemistry

- The study of the relations between chemical reactions and electricity

- Deals with the measurement of electrical quantities (current, potential, charge) and their relationship to

chemical parameters

INTRODUCTION

Why Study Electrochemistry?

- Fabrication of flow detectors

- Electronics

- Electrochemical sensors

- Quality control of industrial manufacturing

- Environmental monitoring

- Biomedical applications
