acidificadj.

Brit.

/ˌasᵻˈdɪfɪk/, U.S.

/ˌæsəˈdɪfɪk/

Origin: Formed within English, by compounding. Etymons: acid n., -ific comb. form.

Etymology: < acid n. + -ific comb. form. In sense 1 after French acidifique (Lamarck Réfutation de la théorie pneumatique (1796) iv. 29).

1. Chemistry. In Lamarck's terminology: designating a form of fire held to be responsible for caustic or acidic properties. rare. Now historical.

1835 Edinb. New Philos. Jrnl. 19 12 When less condensed, and more liable to escape, it is acidific fire (feu acidifique), the cause of causticity when in great abundance, and of tastes and smells when less so.

1901 A. S. Packard Lamarck viii. 120 The salts, pyrites, and metals only differ from other minerals by the different circumstances under which they were accumulated..and in their much greater amount of carbonic or acidific fire.

1981 L. J. Burlingame in H. Woolf Analytic Spirit i. 77 In its ‘acidific’ form it [sc. fixed fire] was found in imperfect compounds which were more or less soluble in water and incombustible.

†2. Mineralogy. In J. D. Dana's terminology: designating an element (esp. oxygen or sulphur), which combines with a basic element and an acidic element to form a salt or salt-like mineral. Cf. acidic adj. 1a. Obsolete.

1868 J. D. Dana Syst. Mineral. (ed. 5) Introd. p. xv Ternary compounds (called also salts and double binaries) consist of elements of three kinds, (1) basic, (2) acidic, (3) acidific. Thus..sulphate of lead contains (1) lead, (2) sulphur, (3) oxygen; the sulphantimonite, jamesonite, contains (1) lead and iron, (2) antimony, (3) sulphur.

1882 H. B. Cornwall Man. Blowpipe Anal. ii. 31 The reduction of a compound signifies the abstraction of oxygen, chlorine, sulphur, or some other acid or acidific element from the metallic or basic element.

3. Containing or generating acid.

1930 Brit. Patent 310,976 1/1 If acidific materials are to be filled into the tube, it is advantageous to make the tube of acid proof material like cellophan.

1976 Jrnl. Amer. Chem. Soc. 98 2876/1 This basic solution was..acidified. This acidific solution was continuously extracted with ether for 16 h.

1997 Ecol. Monogr. 67 348 Acidific fens and swamps.
