Notebooks preparative formats

Laboratories should require that any reaction mixture stored in glassware be labeled with its chemical composition, its date of preparation or formation, the name of the laboratory worker responsible, and a notebook reference. This procedure can provide the information necessary to guide disposal of the mixture if the responsible laboratory worker is no longer available. It should be recognized, however, that such a procedure must be enforced. It cannot guarantee that a departing worker will not leave behind unlabeled mixtures. 

Individual instructors vary greatly in the type of notebook format they prefer such variation sfems from differences in philosophies and experience. You must obtain specific directions from your own instructor for preparing a notebook. Certain features, however, are common to most notebook formats. The following discussion indicates whaf mighf be included in a typical notebook. 

Synopsis of and Notes on Experimental Procedure—Results. Enter a one-or two-line statement for each part of an experiment. Reserve sufficient room to record results as they are obtained. As noted in Section 1.5 of "Notebook Format for Preparative Experiments," do not copy the experimental procedure from the textbook, but provide a synopsis of it.
