| nitridation | Formation of nitrides; formation of nitrogen compounds through the action of ammonia (analogous to oxidation). (05 Mar 2000) |
| nitride | <chemistry> A binary compound of nitrogen with a more metallic element or radical; as, boric nitride. Origin: fromNitrogen. Source: Websters Dictionary (01 Mar 1998) |
| nitrification | 1. <chemistry> The act, process, or result of combining with nitrogen or some of its compounds. The act or process of oxidizing nitrogen or its compounds so as to form nitrous or nitric acid. 2. A process of oxidation, in which nitrogenous vegetable and animal matter in the presence of air, moisture, and some basic substances, as lime or alkali carbonate, is converted into nitrates. The process is going on at all times in porous soils and in water contaminated with nitrogenous matter, and is supposed to be due to the presence of an organised ferment or ferments, called nitrification ferments. In former times the process was extensively made use of in the production of saltpeter. Origin: Cf. F. Nitrification. See Nitrify. Source: Websters Dictionary (01 Mar 1998) |
| nitrifier | <chemistry> An agent employed in nitrification. Source: Websters Dictionary (01 Mar 1998) |
| nitrify | <chemistry> To combine or impregnate with nitrogen; to convert, by oxidation, into nitrous or nitric acid; to subject to, or produce by, nitrification. Origin: Niter + -fy: cf. F. Nitrifer. See Niter. Source: Websters Dictionary (01 Mar 1998) |
| nitrile | <chemistry> Any one of a series of cyanogen compounds; particularly, one of those cyanides of alcohol radicals which, by boiling with acids or alkalies, produce a carboxyl acid, with the elimination of the nitrogen as ammonia. The nitriles are named with reference to the acids produced by their decomposition, thus, hydrocyanic acid is formic nitrile, and methyl cyanide is acetic nitrile. See: Nitro-.
