A Laboratory Guide In Qualitative Chemical Analysis Classic Reprint

Excerpt from A Laboratory Guide in Qualitative Chemical Analysis The method of instruction presented in this little book has been developed by the author in teaching the subject during the past fourteen years. The course differs materially from those usually employed, and has given satisfaction because of its tendency to obviate thoughtless and mechanical work on the part of the student - facts which may be offered as an excuse for adding another to the great number of works on qualitative analysis. The general plan of Part I, which is applied wherever it would not be too cumbersome, consists in giving directions for analyses without mentioning the results, and in requiring the student to determine for himself the results of the operations. Following this system, the student almost invariably performs his preliminary experiments with great care, because he recognizes their object and importance. This is especially the case if the student understands that, in the analysis of unknown mixtures, he will not be allowed to use any tables or abbreviated schemes of analysis.

Excerpt from Qualitative Chemical Analysis: A Laboratory Guide In this edition, the greater portion of the text has been rewritten and new material added, although the general plan of the original work has been retained. Under "Laboratory Exercises" a large number of chemical equations have been introduced for the purpose of emphasizing the reactions. The lists of questions at the close of each group of elements have been enlarged. In Part V, tables of chemical compounds have been added. Part VI is entirely new. This includes the less common elements, which are important on account of their technical use. This section will be of value to those desiring an extended course in qualitative analysis. The author trusts that this edition will prove useful as a classroom guide, and that it will offer concise and accurate information as a reference work in the field of qualitative chemical analysis. The author's acknowledgments are due to Dr. J. C. Olsen for valued criticism and to Mr. J. P. Kelly for his assistance in reading the proof.

Excerpt from Qualitative Chemical Analysis: A Guide in Qualitative Work, With Data for Analytical Operations and Laboratory Methods in Organic Chemistry Since the last revision of this very comprehensive text on Qualitative Analysis was issued, a considerable number of new methods of analysis have been published, and some of these have been found to be valuable and have come into more or less general use.

Excerpt from A Laboratory Manual of Qualitative Chemical Analysis for Students of Pharmacy Qualitative analysis is of use to the pharmacist in testing chemicals for identity and purity. The study of the subject is also Of value because Of the practical knowledge of chemicals and chemical processes acquired by the student, and because it gives training in careful observation and develops the reasoning powers as they are exercised in the interpretation of results. This Manual was prepared as a guide for the author's own classes, and the objects sought are to acquaint the student with the general methods Of qualitative analysis and to prepare him to carry out such qualitative tests as the pharmacist may be called upon to make. The course is arranged to include one hour of lecture, one hour of recitation and about three hours of laboratory work per week for one school year. Practice on the analysis of unknown solutions is provided for throughout the course. This is important, as it not only increases the interest of the student in the work but also develops his self-reliance by constantly putting him upon his own responsibility in doing his work and in interpreting his results. The introductory section on the theory Of chemistry may be omitted if it is not necessary for the class to study or review this part of the subject. The Manual is in no sense a reference book, and in general only those things are included that are needed as a guide for the labora tory work, or which may easily be learned in connection with this work. A standard reference book on qualitative analysis will be Of great service while taking the course, and such a reference book is indispensable for anyone who is to pursue the-subject further.

Excerpt from Elementary Qualitative Analysis: A Laboratory Guide Tms manual is offered as a laboratory guide for stu dents of qualitative analysis who have had a year's work in general chemistry. It is the outgrowth of several years' experience with students registered in the varied courses of a university curriculum. The aim in the prep aration of the book has been to systematize the work as much as possible, yet to avoid encouraging rule of thumb work in the laboratory. Our viewpoint has been to give a sufficient number of well-organized characteristic reactions accompanied by appropriate questions to stimulate and encourage analytical thinking. The attempt is made to bring out the value of differential behavior toward reagents early so that the student has at the commencement of his qualitative study an idea of the ultimate application of the reactions. We do not deem the study of the reactions used in the schemes followed in the systematic procedure for the analysis of unknowns sufficient to give the student a grasp of qualitative analysis. The use of analytical questions bearing on the reactions studied has an inesti mable value in the student's analytical training and greatly broadens his knowledge of the chemistry of the metals.

The methods of analysis given by Fresenius are chiefly used, but a number of changes have been made where experience has shown them to be advantageous on account of simplicity or accuracy. A few novelties are introduced in the way of details of processes or combinations of methods, but it may be stated that these have been thoroughly tested and may be relied upon as trustworthy. An original method, now published for the first time, is used for the detection of chlorides in the presence of bromides.
