Equations for all reactions should be written out in your lab notebook before comingto the laboratory. Also, any calculations required (e.g. theoretical yield, preparation ofsolutions) should be written in full in your laboratory notebook before coming to thelaboratory. Record all observations in the lab book including any color changes,unexpected events, smells, etc. The notebook will be marked from time to time duringthe term. Plan your working time in the laboratory! By doing this your laboratory willbe a useful and pleasant experience rather than a frustrating one.ALL LABORATORY EXPERIMENTS MUST BE DONE DURING THE ALLOCATEDTIME PERIOD. THERE WILL BE NO EXTENSION OF THE LAB AND NOADDITIONAL TIME PERIOD AVAILABLE FOR THE EXPERIMENTS, except underspecial circumstances such as illness verified by a doctor’s note.1.Keep benches clean and orderly and sinks clean. You must leave your portion ofthe bench and all glassware and equipment clean at the end of the lab period.2.Aisles and floors are to be kept free of obstructions. Keep cupboard doors anddrawers closed when not in use.3.Hang coats on the rack. No coats are permitted on tables or benches.4.Laboratory doors MUST be unlocked during lab period.1.6GUIDELINES FOR PREPARATION OF LABORATORY REPORTS
CBE2207Edited by J. Herrera, 2017Laboratory Manual16Laboratory reports should be written as though they were short technical reports. ThusTables and Figures should always be referred to in the prose text of the report, i.e.they should not appear on their own.The report should be written in the past tense, since it is a description and a correlationof past observations. The present tense may be used in referring to laws of nature,properties of materials etc. which are independent of time. Thus, for instance, in aparticular experiment “The ambient temperature equaled 22C”; on the other hand,“The ambient temperature equals about 20C ”.TITLE PAGETitle of experimentName of person writing the reportName of experimentersDate when the experiment was performedAll Formal reports must be TYPEDABSTRACTThe Abstract should summarize the entire report. It should state clearly and brieflythe objectives, methods, results and conclusions of the lab.Objective:State the objective or purpose of the labMethod:In one or two sentences, summarize the methods, including scientificand common names of chemicals and techniques used.Results:Summarize what was found in the studyConclusions:State the significance of the results in relation to the objective.
CBE2207Edited by J. Herrera, 2017Laboratory Manual17INTRODUCTIONThe Introduction should describe the scope and the purpose of the lab and includeany background information necessary to understand the experiment.
