SYNTHETICINORGANIC CHEMISTRYDIRECTIONS FOR WORK
The course outlined in this book is an experimental study of
chemistry. Chapters I and III deal with general principles.
The first part of each of these two chapters gives directions for
experiments which are to be performed by the student. Records
of these experiments are to be kept in the laboratory note book as
follows: the experimental facts and measurements are to be re-
corded on the left-hand page as the note book lies open; opposite
these statements, on the right-hand page, calculations are to be
made, equations for the chemical reactions are to be written,
and final conclusions are to be drawn. The second part of each
of these chapters is devoted to notes discussing the principles that
the experiments illustrate, and problems for home work.
The other nine chapters are devoted to preparations and ex-
periments which reveal the properties of the various classes of the
chemical elements and their compounds.
Preliminary Reports on the Preparations. Before beginning
work on a preparation the student should have a clear knowledge
of the whole procedure and should understand the reactions as well
as the application of chemical principles to these reactions.
To that end study carefully the general discussion of the prep-
aration as well as the procedure. On the left-hand page of the note
book (1) write a brief discussion of the fundamental principles
involved in the preparation; (2) write equations for all reactions;
and (3) starting with the given amount of the principal raw
material, calculate what amounts of the other substances are nec-
essary to satisfy the equations. When the amount specified in
the directions is different from that calculated, state the reason for
the difference. Calculate also on the basis of the equations the
amount of the main product as well as of any important inter-
mediate products or by-products.
