Neutralization
The admixture but broad flame, something like the flame of of an alkali or base with an acid in such pro- an ordinary gas burner. The tube is placed portions that neither shall predominate. A in this flame and turned around until a good neutral compound neither turns turmeric pa- heat is given to the tube; it is then withdrawn per brown, nor litmus paper red. The term from the flame and bent, when it does so with saturation is also applied to complete neutral- a perfect curve and no collapse on the sides of ization (see No. 27); but saturation has two the tube. Of course this is only intended for distinct meanings; chemically, it denotes that the smaller tubes, but a tube of one-third of a given alkali has been neutralized completely an inch and more can be thus bent very by an acid, or vice versa. Pharmaceutically, readily. it implies that a given solvent is charged to its utmost capacity with an active ingredient; this point is, however, so difficult to determine, that the term is scarcely ever applied accurately.
