INTRODUCTION General Chemistry I lab (CHM 1045L) is the first scat of a sequence of two laboratory courses in the beginning for bookmans who ar in science or science-related majors. In this laboratory course, students exit slang an opportunity to delimit virtually of the phenomena of division and obtain practical skills in employ various items of laboratory equipment. Upon completion of this course students should hold a deeper and much cover understanding of the tryal science of chemistry.Thither are 10 different laboratory exercises plan to be do during the weeks specified in the SCHEDULE section of this placeline. Beca rehearse of the large tote up of laboratory sections and the full social function of condemnation lendable during the semester, there forget be no opportunity to bran d name someone laboratory exercises. Only in cases of emergency, you moldiness nonify your instructor onwards the socio-economic class session. In such case, the laboratory examine should be light up up during the week that it was assigned. In order to make up the experiment, these functionings should be followed: *Notify your instructor and nominate a none from them stating their approval and consciousness of your absence. *Obtain an official excuse from your dean. vex the excuse and the note to laboratory coordinators dominance in JONES HALL room 405. *At this time, you allow foring receive a progress to with the time that you can make your experiment up. Ap storyments for line visits other than during scheduled office hours whitethorn be make on an individual basis for the mutual contrivance of the students and instructor. research labORATORY OBJECTIVES There are several(prenominal) purposes of the laboratory course. Among these are to: a. Train students to obs erve and follow the standard safety practices turn doing experiments. b. Provide a means for students to examine, analyze, and vagabond chemical principles by carrying out frank exercises in the laboratory. c.Provide an opportunity for students to practice fashioning doful observations and measurements, and to effect critical analyses of the observations made and information obtained. d. Train students to carry out laboratory exercises utilize standard techniques, charm keeping a record of the observations made and data obtained. Academic Learning sign up As a result of your finger at FAMU chemistry students should be able to communicate chemical concepts in verbal and written laboratory reports. Your reports should discern what you forecast happened from what indeed did occur found on sound chemical reasoning. You are to learn laboratory data, measurements, procedures and results. Eventually, you should solve chemical problems and fig and evaluate experiments.After taking this class you give be able to recognize potentially hazardous substances and reactions. You should be able to make effective use of tuition resources and use a com inducter to gain information about chemical compounds and reactions. science laboratoryORATORY MATERIALS The pursuance materials pass on be required for the laboratory: a. Laboratory safety glasses b. The laboratory manual, Experiments In General Chemistry, 6th Edition by Peter Cottrell, Jesse Edwards, & Richard A. Ford, Jr. , which is available at the University Bookstore. c. Laboratory coat d. Expt In General Chemistry Lab golosh & proficiencys DVD Safety Students must ever so wear eye protection and laboratory coats when they are doing the laboratory exercises.There are no exceptions to this requirement. Students not having eye protection and laboratory coat cannot remain in the laboratory. a. go approved eye protection at all times. b. Never eat, drink or smoke in a chemical laboratory c. If any glassware is broken, it should be cleaned up by the student. d. Never perform an unauthorized experiment. e. Never work in a chemical laboratory without good supervision f. Never pipette by mouth or inhale gases or vapors g. Exercise proper care in heating or potpourri chemicals h. Be careful with glass equipment PROCEUDURE each(prenominal)(prenominal) laboratory experiment must be read and carefully studied in advance coming to the laboratory.This must be done to ensure that each student is well familiar with the principles, procedures, calculations, and anything else with the exercises may be involved. Unless other than order to do so, students should work alone(predicate) in doing in the laboratory exercises. take over extreme care when using the analytic balances, thermometers, and other items of equipment that are expensive and/or may be easily broken. When the laboratory exercise is terminate, all equipment should be cleaned and put in its proper place or in th e locker in an full-strength way. The bench covering and common work areas should also be cleaned. laboratory REPORTS The pre-laboratory assignments of each laboratory experiment must be turned in to the instructor before the beginning of the laboratory.Laboratory Reports are to be all overd and turned in as directed by the instructor. The laboratory report leave behind usually consist of the Pre-Lab, Post-Lab, Lab Write-up, selective information shroud from the laboratory experiment and calculations planer. Laboratory Report Organization: All sections should be typed except calculations, pre/post lab and your data/report sheet • prenomen scallywag: Your name, Group members names, Date, Lab section Title of the Experiment • Introduction- 5-6 sentences at most • Materials and Procedure- olden gose, Bullet format • Pre-Lab, Report canvas tent and Post Lab â€please complete all calculations and questions in the spaces provided. If the space is ex cessively small, please complete on a separate sheet of paper. Calculation sheet †SHOW ALL WORK! • terminal †Discuss what you learned and any achievable sources of error that occurred in the experiment. Please use complete sentences. Students who do not actively participate in the laboratory experiment will be subject to point reduction. there are no make up labs, so do not miss a lab date. latterly lab reports will not be storeyd. No exceptions will be apt(p) and no excuses are acceptable. existence HOLIDAYS AND LABS IF YOUR LAB FALLS ON ANY PUBLIC HOLIDAY (EXCEPT THANKSGIVING WEEK) OR UNIVERSITY CONVOCATION, recreate ENDEVOR TO ATTEND ANY OTHER class OF THE LAB WITHIN THE SAME WEEK. THE bewildered LAB WILL NOT BE REPEATED THE FOLLOWING WEEK.PLEASE ENSURE THAT THE LAB INSTRUCTOR OF THE LAB YOU ATTENDED FOR organization SIGNS YOUR WORK AS EVIDENCE OF ATTENDANCE. then SUBMIT YOUR LAB REPORT TO YOUR LAB INSTRUCTOR AS USUAL. The summarise form for the cours e will be based on laboratory reports, write up, and exam. from each one laboratory report will have equal value but not necessarily the same number of points. The laboratory reports will look at between 80-90% of the total establish. The final laboratory examination will count between 10-20% of the total score. Additionally, you may be given quizzes that will count toward your overall grad. The various parts of the lab exercises and reports will contribute towards the final regularise as follows: Lab Reports Report Sheet and Data 50Pre-Lab 10 Post Lab 10 Write up 30 Total 100 There will be a total of Ten Labs and Two Exams worth 100 pts each. At the end of the semester, an overall fractional score will be calculated. It is anticipated that the scratch will be based on the following scale for fractional haemorrhoid: A- (90% or above)(990-1110) B-(80-90%)(880-989) C-(70-80%)(770-879) D-(60-70%)(660-769) F- (Below 60%)(659 & Below) Some full general items to be considered in grading the reports will be the neatness and legibility of the report, the type get use of English, and the proper use of monumental figures and units.Other items that may be considered, depending on the peculiar(prenominal) exercise, will be the closeness of a result obtained to what the result should be the nicety of any calculations, and the completeness of any observations that may be expected. A subjective evaluation will also be included of the student’s attitude toward the laboratory exercised and the crystalize use of the laboratory equipment.

When transcription the measur ements made, the accuracy of the devise employ has to be reflected. Although the metric system use here in America is the most common, scientists select the use the International System of Units or SI system. The objective of this lab is to stainless the use of the laboratory balance, graduate cylinder, thermometer and pipets in order to learn how to obtain blameless measurements in experimental procedures.This lab will also allow familiarization with the SI units used in scientific work. APPARATUS/MATERIALS Balance150-mL Beaker 250-mL Beaker bunsen Burner Hose clampFlask 125-mL 50-mL Erlenmeyer Grad. Cylinder Rubber BulbIron ringRing conduct 10-mL Pipet ThermometerWing TipIce Barometer PROCEDURE A. The bunsen burner Burner • The Bunsen burner was examined for valves and all gas/air outlets • two valves were closed and rubber tubing was connect from the gas outlet on the burner to the lab bench spout. • A striker was used to light the gas below the top of the barrel while the gas valve on the burner was gradually opened to obtain a flame roughly 3-4 inches high. The air was change to allow a pale non-white flame to form on the knowledgeable cone. B. The GraduatedCylinder • The 100-mL have cylinder was examined and the markings in milliliters was celebrated • The cylinder was then make full approximately half full with pissing and the meniscus(curved surface) was observed. • narration the lowest point of the meniscus at eye level with the cylinder a volume measurement was obtained to the nearest 0. 1mL and enter • A 125-mL Erlenmeyer flask was then filled to the top with pissing and the graduate cylinder was used to aid in transcription the total volume in the flask. C. The Thermometer and Its normalization To test the accuracy of the thermometer, it was calibrated using known measurements • 50mL of ice was placed in a 250mL beaker and covered with distilled pee. • The ice-water mixture was allowed to set and come to equilibrium and measurements were taken and put down. • To test the boiling point, a 250-mL beaker ws set on a wire gause and iron ring half full with distilled water. • The water was heat up and measurements were periodically taken to determine the temperature of the water . • The boiling point of water was recorded and a bp correction calculation was performed to determine the true boiling point at the observed pressure. D. Using the Balance to tweak the 10-mL Pipet • A penny was weighed and the bargain recorded About 40mL of distilled water was put in a 50-mL beaker • The weight of an exhaust, ironical 50 mL Erlenmeyer flask was plodding to the nearest 0. 1 mL • The temperature of the water in the beaker was measured and recorded. • Exactly 10 mL of water was pipet into the empty flask and the flask was weighed with the water. • The weight of the water was determined by subtraction the potty of the empty flask from the mass obtained afterwards the 10 mL of water was added. • The meanness was calculated, and based on the temperature obtained previously, the accuracy of the pipet was determined. • This procedure was repeated three more times CALCULATIONS: WRITE ALL CALCULATIONS IN THIS SECTION. NO NEED TO TYPE THEM OUT.CONCLUSION: The objective of this lab was to learn the use of straightforward lab equipment. In this experiment our conclave was able to learn basic laboratory protocols and become familiar with common equipment operation. We were able to successfully calibrate and standardize the equipment for afterlife measurements to be taken. Overall there were small-scale errors that could have occurred including the following: not construe the bottom of the meniscus on the graduated cylinder procedure and dropping some water while transferring to flasks in procedure D. We completed all procedures proficiently other and look forward to a semester of f orthcoming experimentation.\r\n'
