CSUN CHEM 101L Laboratory Manual ii To the Student The laboratory exercises in this manual are designed to help you develop a sense of how science, and chemistry in particular, is done. In addition to learning many essential laboratory techniques, you will learn how to plan experiments, acquire data, record observations, and properly present your findings. You will also learn procedures for working safely in the laboratory. In order to ensure your success in the laboratory, it is very important that you come to class prepared. Prior to your lab period, you should always read through the description of the assigned exercise found in this manual. You will be expected to review short sections in your lecture text, in order to better understand the principles of the experiment. Each activity will also have a short set of pre-laboratory questions. You are strongly advised to do this assignment, in preparation for the pre-lab quiz that will be held at the beginning of each laboratory experiment. Because time is limited in the laboratory, you must plan your course of action in advance. Planning ahead will ensure that you complete the assignment and work safely and efficiently in the laboratory. Students who fail to demonstrate the proper preparation before coming to lab will not be allowed to work in the laboratory. Each laboratory period your instructor will offer a short pre-lab lecture. This discussion will be used to highlight safety provisions, demonstrate proper techniques and equipment use, and discuss any questions you may have. Come to the lab prepared to ask questions about any part of the experiment that you do not understand. For many of the lab exercises you will work with other students in a team. Every student is expected to contribute to the completion of the lab activity. You will be responsible for maintaining an individual lab notebook, and when unknowns are analyzed, each student will have a different unknown and will report separate results.
