Excerpt from A Course in Qualitative Chemical Analysis Detailed methods for the preparation of solutions of definite strength are given for the assistance of the instructor. The value of introducing preliminary experiments in a course in Qualitative Analysis is a mooted question. We believe that they should be restricted to those which are utilized in the schemes of separation. Experience has shown us that it is a good plan to have in the laboratory several sets of bottles con taining solutions of known strength of the salts of the various metals. The students are encouraged to use these to verify any of the preliminary tests in case of doubt. By comparing in special cases the results obtained with known solutions with those obtained with the unknown, a definite knowledge of that particular reaction is fixed in the student's mind. Students should be encouraged to use short cuts, and the use of the preliminary test as a means of indicating short cuts.
