CHEM 221QUANTITATIVE ANALYSISFALL 2010Instructor: Dr. Jason BennettOffice: 31 HammermillPhone: 898-6123Email: [email protected] Class Meeting Times:Lecture: MWF 9:05 – 9:55 am in 120 OBSLab: M 3:35 – 6:20 pm in 105 OBSOffice Hours:Prerequisites: Successful completion of CHEM 112 and 113Credits: 4.0Required Materials:1. Textbook: Quantitative Chemical Analysis 8th ed., D.C. Harris 2. Handheld scientific calculator (bring to class everyday!)3. Safety glasses ($0.50/wk.) or goggles4. Permanently bound quad-ruled notebook for laboratory (no carbon copy or spirals)Course Description:The course is designed to give you the tools to develop an analyticalapproach to chemical problems, while exposing you to a wide range ofprinciples, methods, and instrumentation associated with quantitativechemical analysis. Unlike many courses you are used to, this coursewill require that you apply knowledge to new situations. I can’tstress enough that if you only memorize the material, you will notsucceed in this course!The goals for the course are:1. Develop an improved understanding of chemical principles important inanalytical chemistry2. Improved independent thinking and problem-solving skills as opposed tomemorizing3. Enhanced lab skills so that your data is reliableCHEM 221 2010 Syllabus1Topics:We will cover many topics through the course ranging from classicalanalytical chemistry to more recent instrumental techniquesA. Introduction to analytical chemistryB. Analytical tools and experimental errorC. StatisticsD. Chemical equilibrium and volumetric analysisE. Acid/Base equilibrium and titrationsF. Complexation chemistry/EDTA titrationsG. ElectrochemistryH. SpectrophotometryI. SpectroscopyJ. SeparationsLaboratory:The laboratory portion of the course will consist of 9 experiments. Youneed to learn to be efficient in your time to complete the labs in the allotted 2hours and 45 minutes. You will not be able to come in during othertimes to finish experiments; therefore you are responsible forcoming to lab prepared and having read the experiment.Instead of writing lab reports, this course will teach you how to keep aproper research style laboratory notebook. Your grade for this portion of thecourse will depend mainly on the accuracy of your data (75% of eachexperiment) as well as the format and readability of your notebook (25% ofeach experiment). This means you need to be very careful and conscious ofwhat you are doing in the laboratory and more importantly, why you aredoing it! In addition to the lab, there will also be an assessment of yourlaboratory technique and progress throughout the semester. Thiswill be worth the equivalent of 1 experiment. Do not take this gradelightly as this is intended to boost your grade, but can definitelyhurt it too!Lab notebooks will be due at my office before class the Fridaymorning following the completion of an experiment so that I can gradethem and have them back to you by the beginning of your next lab session!There will be a late penalty of 10 pts per day each day after that. If Iam not in my office when you bring your notebook to me, you can eitherleave it in the basket on my door or the box I usually have outside my door.Please Note that I am not available for questions on Thursdays (except formy regularly scheduled office hour) or Friday morning. THEREFORE DONOT WAIT UNTIL THURSDAY NIGHT TO WORK THROUGH YOUR DATA!!!CHEM 221 2010 Syllabus2Homework:Homework will be assigned with each chapter/topic to give you sampleproblems to help you understand the material. I will assign problems coveringall of the important topics in a given chapter and collect them at the end ofthe chapter! Understand that what is important is that you have a soundunderstanding of the material so do more questions if you feel you need it. Ifyou don’t know where to begin, come see me. Homework questions aregreat starting points for exam questions.The answer to each homework problem is found in the back of your textbook.Additionally, I will provide an answer key online for you to check your results.Please come see me if you have questions, or you want to see how to doproblems other than what I have assigned you. Since the homework is not a significant portion of your grade (see below), Iknow the urge is there to ignore them. However I promise that not staying upon your problem sets will severely impact your grade in the course. Thismeans, don’t wait until the week before the exam to try to cram inall of the problems! You won’t be able to do them all and I won’thave time to help you as much as you will need!Homework will count towards 7% of your grade. Since I will try to have aquick turnaround with grading them and posting the answer key online, NOLATE HOMEWORK ASSIGNMENTS WILL BE COLLECTED! Also, I will drop yourlowest homework grade (including if you don’t hand it in one time).Quizzes:There will be a weekly quiz almost every Monday (except for weeks followingexams) designed to test your understanding of the prior week’s material andprepare you for the upcoming week. These are designed to be short andconcise to test understanding rather than memorization. Only the answer toeach question will be counted, in other words, there will be little partial crediton these questions. At least 1 (maybe more) question(s) on each quiz will involve somethingdirectly related to the homework to reward those who are keeping up withthem, and at least 1 question will also be on the upcoming laboratoryexperiment (so make sure you read the lab before coming to class onMonday).There will be ~10 quizzes throughout the semester, only your best 8 scoreswill be counted. Therefore, no make up quizzes will be given.Exams:There will be 3 major exams and a final exam in this course.
