Présentation de l'éditeur
Sheffield Scientific School, as reference text in connection with a short course of lectures on Chemical Theory. A period of six weeks immediately following the first four months instruction in General Chemistry is devoted to work of this nature. General principles and theoretical topics are discussed with the utmost simplicity, and in particular view of their continued application. During this time recitations and laboratory exercises are adjusted to the particular task of explaining and emphasizing the lecture subjects. It is not the intention to segregate and summarily dispose of much important material by untimely or unduly restricted discussion under the above heading. The purpose is rather to offer very early presentation of leading principles which are of material assistance in teaching the beginner to properly explain and correlate his experimental results. Such preliminary preparation permits very open class room discussion of the specific chemical phenomena, which are gradually developed in the laboratory. Every opportunity for illustrating and applying these principles is improved as the actual chemical experience of the student increases. The advisability of using theE lectrolytic Dissociation Theory and theM ass Action Law in first year work is no longer questioned by most teachers. It is rather a question of when and how these subjects should be introduced. As soon as the student has acquired practical familiarity with the molecular and atomic theory and is able to fully comprehend a few of the more general types of chemical change, no particular difficulty will be met in studying the characteristic behavior of electrolytes in aqueous solution, or the effect of enforced concentration changes (formation of gaseous or insoluble products) on the course of a reaction.
