Excerpt from An Introduction to the Science and Practice of Qualitative Chemical Analysis Inorganic

The principal aim of this volume is to guide the student towards the attainment of systematic work in his qualitative analysis - to help him to learn a sound method rather than to fill his mind with innumerable isolated reactions.

For teaching the method of work, it is not only unnecessary but undesirable to attempt to include either all classes of compounds, or all the reactions of those that are considered. The selection made is that which long experience has shown to be the best for the purpose, and at the same time it includes all the more commonly occurring inorganic substances.

The reactions described are not only those utilised in the tabulated method given, but sufficient for the more advanced student to avail himself of in devising other methods in specific cases that can be advantageously treated in a special or different manner. A perfect system is an elastic one that may be adapted to various circumstances, and the student is encouraged to consider the tables given as guides rather than rigid rules, when he has had a little experience and can judge for himself.

There is a great deal more given in the book than it would be desirable for a student to actually confirm for himself while going over the reactions for the first time. Those parts that he should experimentally verify as far as he can before beginning any separations are indicated by asterisks, which signify that he should confirm for himself the statements in the paragraph so marked until he comes to the asterisk.
