Revised on March 22, 2020 for Online Virtual Laboratory  Chemistry:   Spring 2020 Course Syllabus    NJIT Academic Integrity Code: All Students should be aware that the Department of Chemistry & Environmental Science (CES) takes the University Code on Academic Integrity at NJIT very seriously and enforces it strictly. This means that there must not be any forms of plagiarism, i.e., copying of homework, class projects, or lab assignments, or any form of cheating in quizzes and exams. Under the University Code on Academic Integrity, students are obligated to report any such activities to the Instructor.   COURSE INFORMATION   CHEM 221 Course Description: The objective of this course is to teach the students the science of chemical measurements. Often, scientists and engineers are faced with the question, what is in a given sample, and how much? Chemical measurement or analytical chemistry is the systematic study of methods which can be used to answer these questions.  This course has been designed for students taking their first laboratory course in quantitative methods of chemical analysis. The topics covered fall under the general category of Analytical Chemistry. By the end of the semester, the students are expected to have acquired fundamental knowledge to prepare them to embark upon a rational approach to qualitative and quantitative analysis. After reviewing the large number of topics and experiments that could have been included here, we have selected a small set of diverse experiments that we believe will provide fundamental knowledge of various popular and powerful analytical techniques. These experiments include data evaluation, gravimetric, complexometric/volumetric/potentiometric titration, and UV-Vis molecular spectrophotometry.  It will be to the student’s advantage to continue to read and reread the chapters in their textbooks on laboratory techniques throughout the semester. There are also some practical aspects of chemical analysis that are best learnt during the experiments. For example, you will learn that one should not use a graduated cylinder for accurate volumetric measurements, and that solids are best dissolved in a beaker covered with a watch glass. The laboratory professor or teaching assistant (TA) will usually explain and/or demonstrate these and many more techniques which have been used successfully over the years.  Students are encouraged to ask questions before it is too late and the mistakes have already been committed.

CES takes these policies very seriously and enforces them strictly.   Grading Policy: The final grade in this course will be determined as follows:  Seven labs (each 10%) 80% Two quizzes (each 5%) 5% Exam (ORAL PRESENTATION ONLINE) 10% Lab behavior and lab cleanness  5%  Your final letter grade in this course will be based on the following tentative curve:    A 90-100 C 70-75 B+ 86-89 D 60-69 B 80-85  F  <60 C+ 76-79             Makeup Exam Policy: There will normally be NO MAKE-UP QUIZZES OR EXAMS during the semester. In the event that a student has a legitimate reason for missing a quiz or exam, the student should contact the Dean of Students office and present written verifiable proof of the reason for missing the exam, e.g., a doctor’s note, police report, court notice, etc. clearly stating the date AND time of the mitigating problem. The student must also notify the CES Department Office/Instructor that the exam will be missed so that appropriate steps can be taken to make up the grade.   Cellular Phones: All cellular phones and other electronic devices must be switched off during all lab times. Such devices must be stowed in bags during exams or quizzes.
