Excerpt from Practical Physical Chemistry
The theoretical significance of physico-chemical constants, and the fact that they find their application in almost every branch of chemistry, renders it essential for all students of the science to become familiar - to some extent, a... t any rate - with physico-chemical methods.
It is not possible Within the limits of a small volume such as this to deal With every phase of the subject. I have, therefore, chosen such experiments as Will demonstrate the fundamentals of the subject, in order that, in the first place, the student may familiarize himself With physico-chemical measurements, and secondly, that he may fix more firmly in his memory the knowledge that he has already gained in the lecture theatre. If a science is to really live, it is essential. That theory and practice should go hand in hand. One principle demonstrated by the student himself is of far more value to the student than pages of lecture notes.
The importance of spectrum analysis seems to have been overlooked in the past, but it is the Opinion of the author that the student should at least be familiar with the principal features of the subject, such as mapping of spectra and determination of wave-lengths, etc.; therefore a short chapter on this subject finds a place in the present volume.
