    LIST OF REAGENTS, APPARATUS, AND INSTRUMENTS A. REAGENTS IN GENERAL USE These are to be used, unless otherwise directed, in the strengtli here given. In the case of officinal substances the pharmacopoeal strength (B.P.) is selected. Reagents directed to be used in dilute solution are to be treated with water in the proportion of 1 part reagent to about 10 parts of water. 1. Strong Acetic Acid 96 per cent.; specific gravity 1 064. (The glacial acid with about 3 per cent. of added water.) 2. Strong Hyurocheoric Acin Specific gravity 1T6. 3. Strong Nitric Acid In Order to render it suitable for all purposes it should be exposed to the light tili it assumes a somewhat yellow colour. 4. C.vusTic Soda Solution Should contain 15 per cent. of NaOH and have a specific gravity of 1T59-1T63. [Li«?. sodcp (B.P.) is too weak.—Tra?ifil.] 5. Satür.vted Solution of Common Salt 26 per cent.; specific gravity 1'201. 0. Half-saturated Solution of Chlorinated Lime Prepared by diluting a saturated solution of Calx Chlorinata (B.P.) with an equal volume of water; it must be freshly inade froni tirne to time. 7. Perchloride of Iron (Liq. Ferri Perchlor. B.P.) Specific gravity ITl. Always has an acid reaction, but must not contain anv fi’oe acid, and when treated with ammonia mnst give a precipitate of iron hydroxide whicli persists on shaking.
