Office hours: 2:00-4:00, T 8:00-10:00, W 2:00-3:00, Th 9:00-11:00, and others by appointment

Text and supplementary materials: Lab handouts will be given to you during the semester. You will need a laboratory notebook (the carbon-copy kind), safety glasses, a scientific calculator, and a diskette on which to save your lab reports.

Lab: T, Th 2:00-5:00 pm PH 137

Course Policies:

• Class attendance is expected unless the student experiences a health problem or unless there are extenuating circumstances. Divisional policy states: “A student is required to attend 70% of all class meetings or receive an automatic “F”. This policy is more rigorous than the university’s 50% requirement.

• Please come to class on time. We will begin on time. Tardy arrivals are a sign of disrespect to the professor and the other students.

• Please try to briefly skim through the chapter before the corresponding lectures because I prepare my lectures according to this expectation. You will benefit much more from the lecture having skimmed the chapter ahead of time.

Turn off your cell phones before each class. Put them away and do not take them out during class. If your cell phone rings or vibrates during class, you will have to leave class for the day. If it happens again, you will have to leave class and you must talk to me before you return. These same penalties apply for answering text messages or for using your cell phone as a calculator. Basically, do not take out your cell phone for any reason during class.

Desired Student Goals and Outcomes and Nature of the Course:

Following is a list of lab experiments to be covered during the semester and expected student goals associated with each.

SEQUENCE of TENTATIVE LECTURE TOPICS (subject to change)

Weeks 1-2

Analysis 1: Gravimetric Determination of SO4-2 in a Soluble Sulfate Sample-The student will use gravimetric analysis to determine the percent sulfate in an unknown sample.

Weeks 3
  • Analysis 2: Precision Titration Techniques-The student will learn and practice the fundamentals of titrations.
Weeks 4
  • Analysis 3: Titrimetric Determination of Na2CO3 in Soda-Ash Sample-The student will use titration to determine the percent Na2CO3 in an unknown soda ash sample.
Weeks 5-6
  • Analysis 4: Spectrophotometric Determination of Fe with 1,10-Phenanthroline-The student will use 1,10-phenanthroline and spectrophotometry to determine the percentage of iron (Fe+2) in an unknown.
Weeks 7-8
  • Analysis 5: Spectroscopic Determination Concentrations in a Permanganate-Dichromate Mixture-The student will use spectroscopy to determine the concentration of permanganate ion and dichromate ion in an unknown mixture.
Weeks 9
  • Analysis 6: Determination Ca+2 in Calcium Gluconate-The student will use titration with EDTA to determine the percentage of calcium in an over-the-counter calcium gluconate tablet..
Week 10
  • Analysis 7: Iodometric Titration of Vitamin C. (Page 796 in text)-The student will use iodometric back titration to determine the ascorbic acid in an over-the-counter vitamin C tablet.

Week 11

  • Analysis 8: Volhard Determination of Cl- Ion-The student will use the Volhard method to determine the percentage of chloride ion in a salt sample.

Week 12

  • Analysis 9: Determination of Fe by Potentiometric Titration-The student will use potentiometry to determine the percentage of iron in an unknown ferrous ammonium sulfate sample.

Week 13

  • Analysis 10: Determination of pKa of BromothymolBlue-The student will use spectrophotometry to determine the pKa of an acid-base indicator.

Requirements of the Course:

Requirements of the course include quizzes and lab reports. Descriptions are as follows:

Quizzes:

  • To encourage you to familiarize yourself with the concepts behind the labs, twenty-point quizzes will be given at the beginning of lab every other Thursday unless stated otherwise. Makeup quizzes will not be given. You will have at least five quizzes in all, which will count for a possible 100 points. Because the lecture and the lab are intertwined, you can also expect to see information from lab on lecture quizzes and exams.

Lab Reports:

  • Laboratory work consists of ten analytical determinations. The lab reports will be worth 20 points each. The lab reports will be due one (1) week after the lab is finished. Precision and accuracy will be used as a criterion for grading with accuracy being the most important. You will also be graded on the substance of your lab report: objective, introduction, data, calculations and/or observations, and conclusions.
  • Substance of the lab report (50%)Accuracy of results (50%)

Objective: 1 pt.0-2% error: 10 pts.

Introduction: 1 pt3-5% error: 8 pts.

Data/Observations: 2 pts.6-10% error: 6 pts.

Calculations: 3 pts.11-15% error: 3 pts.

Conclusions: 3 pts.16-20% error: 0 pts.

Methods of Evaluation:

The student will be evaluated based on his/her performance of the requirements listed above (quizzes and lab reports). The grading policy is as follows:

Grading:

  • A ten (10) point scale will be used to determine the final grade. So, for example, 91% would be an A-, or 75% a C. Adjustments of this scale will occur at my discretion. Any curve I do construct will be based on my discretion.
  • Point distribution is as follows:

Lecture Quizzes100 pts

Exam I100 pts

Exam II100 pts

Exam III100 pts

Homework100 pts

Lab reports200 pts

Lab quizzes100 pts

Final Exam150 pts

Total950 pts

Disabilities Statement:

  • It is the responsibility of students who have professionally diagnosed disabilities to notify the instructor with documentation from Academic Support Services, so that necessary and appropriate modifications can be made to meet any special learning needs.
Academic Dishonesty Statement:
  • Your catalog informs you that students at Mississippi University for Women agree to uphold the school’s honor code and refrain from any academically dishonest behavior including cheating, plagiarism, falsifying of data (relevant in laboratory settings), and any other intellectually unethical behavior. It is your responsibility to make yourselves aware of the university’s policies on academic dishonesty as stated in your catalog since those policies are applicable in this class. Your punishment could range from a zero on an assignment to an appearance before the Academic Standards Board. Your university’s accreditation is based, in part, on academic standards of excellence. If you cheat, you will devalue your MUW degree.
