Book excerpt: 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. 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.
