PRACTICAL CHEMISTRY.

[Special stress will be laid upon the written record of your work, and your attention is directed to the following points:

(a) Give a concise account of all the steps of the processes you employ, and of all the tests you use in searching for the different substances.

(b) If you find a metal capable of forming two series of compounds, ascertain, if possible, to which of these series the metal present in the substance you are examining belongs.

(c) In testing a solid, dry way tests, in addition to wet way tests, must be employed.

(d) In testing a solution, dry way tests should be employed in all cases where it is advisable to do so-in addition to liquid tests.

(e) Use confirmatory tests where it is possible to do so.

(f) At the end of your paper, give a statement of the constituents found in each solid or solution given you for examination.]
