rhodizonicadj.

Brit.

/rəʊdɪˈzɒnɪk/, U.S.

/ˌroʊdɪˈzɑnɪk/

Origin: A borrowing from Greek, combined with an English element; modelled on a German lexical item. Etymons: Greek ῥοδίζειν , -onic suffix.

Etymology: < Hellenistic Greek ῥοδίζειν to be rose-like (see rhodizite n.) + -onic suffix, after German Rhodizonsäure rhodizonic acid (J. F. Heller 1837, in Ann. der Pharm. 24 8).

Chemistry.

rhodizonic acid n. a crystalline dibasic acid whose salts are used in solution as analytic reagents to detect certain metals, esp. barium, which form red or brown precipitates.Systematic name: 5,6-dihydroxycyclohex-5-ene-1,2,3,4-tetrone; C₆H₂O₆.In quot. 1862 referring to a different substance.

1862 Amer. Jrnl. Sci. 83 274 The rhodizonic acid obtained by Brodie, by the action of absolute alcohol on the compound of carbonic oxyd and potassium, has probably the formula C₂₀O₁₆K₆ or C₁₀O₈K₃.

1916 C. A. Mitchell Vinegar ix. 154 Tests of identity have been based upon the oxidation of the sugar into a quinonic compound, rhodizonic acid, some of the salts of which are of a bright red colour.

1955 J. C. Giblin Qualitative & Volumetric Anal. (ed. 2) iii. 77 In this reaction, the barium or strontium salts of rhodizonic acid are first formed as brown ppts.

1991 Arch. Environmental Contamination & Toxicol. 20 423 Lead was leached from ceramic ware with citric acid and identified by rhodizonic acid in this quick, qualitative test.
