hydroxonium1925

1925 Chem. Abstr. 19 2309 (heading) Action of ammonium chloride vapor on metals and similarity of ammonium salts and hydroxonium salts as acids.

1925 Chem. Abstr. 19 2310 This expt. provides an important confirmation of Hantzsch's hydroxonium theory.

1940 Jrnl. Chem. Soc. 1410 When the hydrogen ion is considered to occur (in aqueous solution or in a compound) in the form [H₃O]⁺, it is advisable to call it the hydronium ion (not hydroxonium ion).

1956 Jrnl. Chem. Soc. 2913 (heading) Raman spectra and constitution of solid hydrates. Hydroxonium perchlorate, nitrate, hydrogen sulphate, and sulphate.

1957 G. E. Hutchinson Treat. Limnol. I. iii. 197 Three of the hydrogen atoms could be at 0·99 A. and one at 1·77 A., corresponding to the hydroxonium ion H₃O⁺.

1966 Mineral. Mag. XXXV. 1071 The existence of the individual H₃O⁺ pyramidal complex, called the hydronium ion, or sometimes the hydroxonium or oxonium ion, in crystalline substances is a well-established fact.
