Requirements Fulfilled Chemistry 123 is a Physical Science course in the Natural Science category of the GEC, which has these goals and objectives: Goals/Rationale: Courses in natural sciences foster an understanding of the principles, theories, and methods of modern science, the relationship between science and technology, and the effects of science and technology on the environment. Learning Objectives: 1. Students understand the basic facts, principles, theories, and methods of modern science. 2. Students learn key events in the history of science. 3. Students provide examples of the inter‐dependence of scientific and technological developments. 4. Students discuss social and philosophical implications of scientific discoveries and understand the potential of science and technology to address problems of the contemporary world. Course Expectations “At some point in our lives we must decide if we’re going to have fun and make it work, or work hard and make it fun.” ‐Crenshaw I’m not going to lie, general chemistry here at Ohio State is a ton of work. This course will not be easy, and for the first time in your academic career, you will really have to master the material given to receive an A. Chemistry is considered the “central science,” and many majors require you to know the fundamentals of chemistry. They expect a standard of excellence. Some students refer to this standard of excellence as a “weed out process,” but I will do everything I can to help you succeed in this class, to encourage you, and to motivate you to be the best student you can be. Outlined in this syllabus are the responsibilities and expectations for this course. It also lists the many resources the chemistry department offers, and I encourage you to utilize all of them. This department and this University have so much to offer and I’m proud to be part of this University, I’m privileged to be part of this University, and I can’t wait to get started with the quarter. If you are unable to attend the first lab session, check in at 100 Celeste immediately. Failure to do so will result in you losing your seat for the lab and the course. 1 Dr. Fus – Chemistry 123 Course Schedule – SU11 WEEK LECTURE TOPIC 1ST LABORATORY EXPERIMENT 2ND LABORATORY EXPERIMENT IMPORTANT DATES 1 6/20 Ksp, Factors Influencing Solubility, Group I, Common Ion Effect, Complex Ion Formation (Ch 17.4 – 17.6, Lab Manual) Writing a Proper Formal Laboratory Report Developing a Mastery of the Solubility Product Constant Register Mastering Chemistry Account and complete tutorial quiz 2 6/27 pH Effects, Amphoterism, Q & Ksp, Group II, Selective Precipitation (Ch 17.4 – 17.6, Lab Manual) Developing a Mastery of the Solubility Product Constant (cont.)

Course Approved Calculator: For quizzes and examinations, the use of a calculator is restricted to a TI‐30 (any, except XS Multi view), Sharp EL‐509 (any), Sharp EL‐531 (any), or Casio FX‐250 (any). No other calculators are permitted. [See course webpage for pictures of allowed calculators.] Webpage: https://carmen.osu.edu The Chemistry 123 page on Carmen will serve as a repository for all course‐related materials, including updated syllabi, handouts, study guides, and additional resources. A majority of the online content will be posted as Adobe PDF files, and you are encouraged to install the most current version of Adobe Reader, available free of charge at http://get.adobe.com/reader/. All grades for this course will be posted to Carmen on a regular basis. You are responsible for all updates posted to Carmen, and if you find any mistakes in content or grading, or you need help accessing these materials, please contact your TA or instructor as soon as possible. Student Responsibility Each student receives valuable information about Chemistry 123 in the first and every single lecture section. It is your responsibility to read the material presented in the syllabus and be familiar with the course content, course procedures, and grading. You are also responsible for any announcements concerning course procedures, which are made in class, whether you are present or not. (If you are absent, you are expected to get notes, announcements, etc. from another student in the class.) You are required to have an active Ohio State e‐mail account and are responsible for any announcements made via e‐mail and for any updates made via the course website and the class blog. Attendance Attendance is not taken in each lecture section, but I will do everything in my power to make class enjoyable and worthwhile enough to attend. Ten quizzes will be given randomly throughout lecture, which will make up your quiz grade and no make‐ups will be given. Take a moment to think about why you are attending college. I expect you to attend every single lecture and lab period. That is why you are here. Practice Problems Short problems for each section will be posted on the course website and will also be posted in Mastering Chemistry. These problem sets serve to deepen the understanding of concepts related to the lectures and each laboratory experiment. They are for your benefit and you are encouraged to work them with the effort you might put towards a graded quiz. However, these problems will not be collected or graded, and the answer keys will be posted on Carmen to aid your preparation for the Quizzes. DO NOT WORK THE PROBLEMS WITH THE ANSWER KEY RIGHT BESIDE YOU. THIS IS A GUARANTEED WAY TO LEARN ABSOLUTELY NOTHING. 3 Grading Your final grade will be evaluated on the basis of total points earned. The distribution is as follows: Graded Homework 100 pts. Can take place in lab/lecture/on­line Lecture Quizzes 50 Will take place during the first 5 minutes of lecture Laboratory 250 A minimum of 50% of the lab points is required to pass Midterm I 175 Midterm II 175 Final 250 1000 pts. Your final letter grade is determined based on a statistical distribution determined by the undergraduate chemistry department and is based on your final point total out of 1000. The lecturer can attempt to guess what type of curve will result after each individual exam, but can only speculate untilthe final exam grades are recorded. Graded Homework Graded Homework will be administered on the Mastering Chemistry web‐site. Each student is required to purchase a Mastering Chemistry access code from Pearson Education. The due date for these assignments will be announced at least a week in advance in lecture. These assignments are not short and you should expect them to take 5‐7 hours each. Lecture Quizzes Quizzes will be administered randomly throughout the quarter based on the on‐line lecture videos. They will take place during class using clickers and you are permitted to use your notes. Midterm Exams Exams are given only at the assigned times listed below and shown on the Schedule of Assignments. Make‐up exams will be given only during the last week of regularly scheduled classes for medical reasons (documentation required) or a preapproved university conflict. Exams are a scheduled part of this course and attendance is required (exam locations will be posted on the course website based on lab section). Students with university conflicts must fill out the exam conflict form on the course website and hand it in to the instructor no later than 5:00 pm on the Friday before each exam. In order to receive your exam grade in a prompt manner you will be asked to fill in your SIS (carmen ID) number, so bring it to each exam. FIRST MIDTERM EXAMINATION: WEDNESDAY, JULY 20TH, 6:30 – 7:48 PM SECOND MIDTERM EXAMINATION: WEDNESDAY, AUGUST 10TH, 6:30 – 7:48 PM Final Exam The final exam must be taken at the university scheduled time listed below and shown on the Schedule of Assignments. BUCK‐ID’s will be collected at the final exam and the exam will not be returned to you. FINAL EXAMINATION: TUESDAY, AUGUST 23RD, 11:30 – 1:18 PM 4 IMPORTANT LABORATORY INFORMATION Laboratory Sections The Chemistry 123 laboratory consists of two 3‐hour sessions per week. You may work in the laboratory ONLY during your scheduled laboratory period. Any time remaining in the lab period and the final check‐out period can be used to complete a previous experiment. This must be discussed with your TA first. A minimum of 50% of the lab points are required to pass the course. Safety in the Laboratory Due to the potential dangerous nature of laboratory work, you are reminded to maintain medical insurance coverage through the OSU health service or a private agency when enrolling in Chemistry laboratory courses. Students are required to read, understand, and implement the safety precautions in the laboratory manual and laboratory handouts. The precautions are summarized on a safety form, which must be signed by all students during their first lab period. The following are selected instructions from the safety form: 1. 2. 3. 4. 5. 6. You must wear Department‐authorized ANSI code goggles at all time in the laboratory. Goggles will be issued during check‐in. After the first free pair, goggles may be borrowed, if available, from CE 231 or 331; otherwise, they must be purchased from CE 180. Not wearing goggles will result in the loss of 10% of the grade for the experiment. For any subsequent violation, an additional loss of 10% of the grade will result. Continued violation may result in dismissal from the course. The wearing of contact lenses is not recommended. Each student must wear adequate clothing to reduce the possibility of injury from chemicals or broken glass. Students who wear sandals or shorts will be sent home. No additional time will be provided. Familiarize yourself with the location of the fire blanket, fire extinguisher, and eye wash in the laboratory. Promptly report all accidents, no matter how small, to your lab instructor. Your work area should be cleaned before you leave the lab. After putting your equipment away, wipe down your work area with a wet sponge or towel. This ensures that you, and the other students who use the space, will not be harmed by chemicals left on the desktop. Also clean spills in the balance room by brushing the chemicals into a weighing dish. No unauthorized experiments are allowed. No chemicals may be removed from the lab. Laboratory Notebooks The laboratory notebooks will be graded by each TA at the end of your assigned period. Your TA will be analyzing all your observations made, data collected, calculations, and results. All procedures should be outlined and should be sufficiently neat and organized so that another person can follow what you did. You are required to record all this information in ink in the Student Lab Notebook, which must contain carbon copy pages. At the end of each completed lab, sign and date each page and submit the copies to your lab instructor and they will sign each page and assign you a notebook grade. The following guidelines should be adhered to for each laboratory notebook entry: Before Lab: Complete the Mastering Chemistry Pre‐lab assignment Read the entire lab packet and show up to lab with an open mind willing to learn. Write the Experiment Title and Purpose (one or two sentences in your own words). You do not need to outline the procedure in your lab notebook before lab. During Lab: All of the formulas and equations you have been using in your general chemistry courses are the result of careful laboratory experiments that have been developed, performed, and reproduced time and time again. The details of these experiments can be found in the laboratory notebooks of the chemists who performed the original experiments. During the laboratory period you are required to write a narrative in your laboratory 5 notebook. The narrative basically highlights the key points of what you did indicating all observations and results. Further details of what to include in the narrative will be discussed by your Teaching Assistant in the first lab period. Keeping and maintaining a proper laboratory notebook is one of the most essential skills you can acquire in this course. The lab notebook is the formally kept record of your experiment. It is a true representation of what you are doing in the laboratory. In industry, lab notebooks are the basis of patents, and if necessary, they can be used in a court of law to prove how a particular experiment was performed. A few rules you must follow when maintaining a proper lab notebook: Never erase anything in the notebook. If you make a mistake, neatly cross it out with a single line. Never write in pencil. Write everything in the lab notebook and nothing in the lab manual. If you happen to make a mistake or spill something, write it down. If you observe a chemical or physical change, record it so you can identify it in future experiments. The comments written in the lab notebook will allow you to justify why your experimental values may vary. They also will allow you to compare your results to those of other students in the class. The lab manual not only provides value for you, but also for those who come after you. In a traditional general chemistry lab, you gain very little from merely reproducing the procedure in your lab notebook. If you happen to take all three quarters of general chemistry at Ohio State, you will be participating in some sort of research‐based laboratory experience. In these experiences, it is vital to record your procedure in a manner that a future student could easily follow it. We will refer to this portion of the lab as a narrative and further instructions on how to correctly write a narrative will be given by your teaching assistant. You should be able to perform and reproduce any calculations you write down in your lab notebook and if you were able to use your lab notebook on a quiz or exam, you should be able to answer any questions based on the content or procedure of the lab. After Lab: Follow instructions in the handout given by your TA to complete the formal laboratory report. Complete the Report Questions assigned on Mastering Chemistry. Note: Your Report Questions are due at the assigned date regardless if you attend the lab. Laboratory Reports All formal laboratory reports are due at the beginning of the lab session one week after the completion of each lab. Late reports will be penalized 10% per day. If you submit a late report to 100 CE, you must notify your TA via e‐mail within one day after submission. Zero credit will be given to lab reports submitted after 2 weeks of completing each experiment. Expt.

VIOLATIONS OF THIS STANDARD WILL BE REFERRED TO THE UNIVERSITY COMMITTEE OF ACADEMIC MISCONDUCT (COAM) AS REQUIRED BY FACULTY RULES. If you need assistance, check with the staff of the Department of Chemistry. Group efforts by students, use of another student’s pre‐laboratory or laboratory material, or assistance from individuals who already have taken the course may place you in jeopardy of violation of the standards of General Chemistry. Possession of another student’s lab report(s) will raise immediate concerns about academic misconduct. Plagiarism or the submission of work based on old material is considered to be academic misconduct no matter how small the infraction. Identical answers indicate copying or unacceptable group efforts ‐ always answer questions in your own unique words. Identical answers indicate copying or unacceptable group efforts ‐ always answer questions in your own unique words. Individuals retaking the course must complete all work for the course during the current quarter and may not submit any parts of pre­labs or lab work or reports performed in a previous quarter (see item #6 in “Ten Suggestions for Preserving Academic Integrity”, http://oaa.osu.edu/coam/ten­ suggestions.html). Pre‐laboratory exercises are designed to make you prepare for the laboratory. Copying answers from other individuals or from old copies of the ...
