monocarbonaten.

Brit.

/mɒnə(ʊ)ˈkɑːbənəɪt/,

/mɒnə(ʊ)ˈkɑːbənət/, U.S.

/ˌmɑnəˈkɑrbəˌneɪt/,

/ˌmɑnəˈkɑrbənət/

Origin: Formed within English, by compounding. Etymons: mono- comb. form, carbonate n.

Etymology: < mono- comb. form + carbonate n. Compare earlier bi-carbonate s.v. bi- comb. form 3 and polycarbonate n.

Chemistry. Now rare.

A neutral salt of carbonic acid (H₂CO₃) in which both hydrogen atoms are replaced by a metal.

1854 J. Scoffern in Orr's Circle Sci., Chem. 457 It is a true neutral, or mono-carbonate.

1876 J. Harley Royle's Man. Materia Med. (ed. 6) 152 By continued boiling it [sc. bicarbonate of soda] is further reduced to monocarbonate.

1949 Ecol. Monogr. 19 245/1 It is possible that respiration then [sc. during darkness] produced sufficient carbon dioxide to convert much or all of the monocarbonate to bicarbonate.

1986 Limnol. & Oceanogr. 31 1122 The monocarbonate complex is formed in the pH range 4–5, the bicarbonate uranyl complex between 5 and 6.
