Fluoricity

For many years it was thought that fluorine did not form any 0x0-acids or oxo-acid anions. Recent work, however, indicates the existence of fluoric(I) acid (hypofluorous acid), HFO, formed by the reaction of fluorine with water at 273 K. The acid forms colourless crystals, m.p. 156 K, is very unstable and has, as expected, very strong oxidising properties.

Rotating ring-disk electrodes were employed for an anion effect on the Cu underpotential deposition on Pt(lll) in fluoric and perchloric acid solutions, the results of which were discussed in comparison with UHV results of AES and LEED. ...

It remains to-day to determine the nature of the fluoric radicle, but since the acid has not yet been decomposed, we cannot form any conception of the radicle. 

Haying failed to isolate the element by the electrolysis of hydrofluoric acid and the fluorides, H. Davy tried if the element could be driven from its combination by double decomposition. He attempted to drive the fluoric principle from the dry fluates of mercury, silver, potassium, and sodium by means of chlorine. He said ...

On the whole, it must be admitted that etching by fluoric acid, though practised to some extent, and in some particular cases with marked success, has not been found effective for general purposes. It is usefully applied, however, to form the scales on thermometer tubes, and written or printed inscriptions on glass vessels. The attempt to make it subservient to typographical purposes has been a failure.

Therefore, fluoric acid should never be filled into glass containers Be careful while handling fluoric acid. It is a strong acid, very toxic, and causes severe burns. 

It is apparent from Table 11.12 that ternary acids of fluorine are unknown. There is, however, some evidence that salts of hypofluorous and fluoric acids exist in solution. 

Davy then noticed an analogy between the salts of hydrochloric acid, that is, chlorides, and those of fluoric salts. He inferred the existence of another substance analogous to chlorine, and in 1813 named it fluorine Because of its extreme reactivity, he was unable to isolate it. 

Although the basic chemical reactions have been thought, for many years, to be similar with either sulfuric or hydro -fluoric acid catalyst, extensive work with sulfuric acid described by Albright et al (24) has demonstrated that this is probably not the case. The need for more detailed work with hydrofluoric acid is cited. The following summarizes their report "The reaction mechanism for hydrogen fluoride alkylation also seems to be radically different than that for sulfuric acid alkylation. The alkylation mechanism which has been widely accepted in the past seems to be somewhat more satisfactory for hydrogen fluoride alkylation even though it is not for sulfuric acid...
