Harris; Quantitative Chemical Analysis 8th ed.
A special laboratory notebook (alternating color quadrile paper) is
required.
This course is designed to cover the fundamental principles of chemical analysis. Its purpose is
to give students a strong foundation in applications of chemistry which deal with the identity or
quantity of unknowns. The laboratory portion is a major component in which important skills
are presented which will be utilized frequently in a science career. Problem solving and
attention to detail will be stressed.
A student will demonstrate:
 Competency in standard laboratory and data analysis techniques
 Components of analysis from sampling to statistical analysis
 Application of principles of chemistry to analysis problems
 Understanding of electrochemical methods of analysis

Occasionally, there will be opportunities for bonus points. However, the maximum score
awarded for any graded work will be a 100.
* THIS COURSE REQUIRES A FINAL COURSE AVERAGE OF 70 TO RECEIVE A PASSING GRADE: THIS APPLIES TO MIDSEMESTER GRADE AS WELL.
* THIS COURSE IS EXPERIENTIAL.
MISSING MORE THAN TWO LABORATORY EXPERIENCES WILL AUTOMATICALLY
RESULT IN A FAILING GRADE FOR THE COURSE.
The honor system is alive and well. In this course, I expect that any graded work is your own.
The laboratory in particular has components where group activity is required. However, when
it is time to write your report, it must be your own work unless specifically directed to turn in a
group report.
EXAMS:
You will be required to bring an exam blue book. If you forget, I will supply one but you will
have to give me one to get your graded work returned.
At the conclusion of the examination period (you will have plenty of warning), I will announce
that the work is due and will depart. If I don’t have your paper you will begin accumulating
late points at a rate of 1 point per minute. It is up to YOU to get your work to me. I will not
hunt you down.
The cumulative Final Exam might be on Wednesday, December 11 from noon to 2:30 pm
LABORATORY:
The laboratory portion of your grade is very significant. This course is in part intended
to serve as a lab techniques course. Careful, deliberate attention to detail will pay off richly
here. Sloppy work will show itself with very unfortunate consequences.
The required bound notebook will serve as a journal record of your laboratory
experience. Someone looking at this book ten years from now should have no difficulty
understanding what you did and be able to clearly follow and duplicate your data and analysis.
Each experiment should start on a new page, begin with a brief statement of purpose and a
procedural outline, clearly present the raw data as it was collected. The laboratory notebook is
not supposed to act as a complete lab report, it is just a journal of what happened in the lab.
Copy pages of your notebooks will be turned in on your way out of lab, and a summary report
page will be required. Requirements will be spelled out as we go.
Late report = severe penalty; Reports are not accepted after they are one week late.
The schedule which follows is a plan for the semester, and the chapters listed for each class
period are somewhat approximate, depending on the pace we develop. However, the schedule
accurately reflects the laboratory plan and test days. I will reschedule a test only for amazingly
unusual and unavoidable reasons. (Convenient travel arrangements are not going to qualify.)
DISABILITY SERVICES:
The Office of Disability Services has been designated by the University as the primary
office to guide, counsel, and assist students with disabilities. If you already receive
services through the Office of Disability Services and require accommodations for this
class, make an appointment with me as soon as possible to discuss your approved
accommodation needs. Please bring your accommodation letter with you to the
appointment. I will hold any information you share with me in the strictest confidence
unless you give me permission to do otherwise.
