Excerpt from Exercises in Chemical Calculation
IN common with many other teachers of chemistry, the compilers of this volume believe that the working of suitable numerical examples is the best aid to the under standing of the quantitative aspect of chemical phenomena. The ideal calculations are those made by the student from his own experimental data, but it is necessary for him to use the figures of other workers and the data of ex periments which he himself cannot perform. For this reason the following set of numerical examples has been compiled. It is drawn from recent examination papers and from various original sources. A number of the examples available in examination papers have been rejected because they had no conceivable relation to possible experimental conditions, and were therefore misleading.
In most of the chapters a concise explanatory statement precedes the questions for'solution. It is not intended that this should take the place of wider reading and study, but rather that it should indicate the portions of the text-book relevant to the particular subject under discussion, and provide a brief summary of what should be found there. It is believed, however, that the matter is put in its correct order, that it is in accord with present-day knowledge, and that certain of the beginner's difficulties are explained more clearly than is often the case. Dogmatic' rules for obtaining an answer have, it is hoped been avoided.
