“On the other hand, Sir H. Davy contended that fluoric acid, in its strongest form⟳, is anhydrous; for, on combining it with ammoniacal gas, a dry fluate of ammonia is formed, from which no water can be expelled by heat. He maintained, also, that fluoric acid is composed, not of an infammable base⟳ and oxygen, but of hydrogen united with a negative electric body, analogous to chlorine, to which he has given the name⟳ of fluorine. According to this view⟳, when the metal potassium is brought into contact⟳ with fluoric acid, the hydrogen is not derived from water, but from the acid, and the supposed fluate of potash is a compound of fluorine and potassium. The phenomena are explained with the same ease by either theory, although the arguments upon which they depend⟳ are thought, by the majority of chemists, to preponderate in favour of the view⟳ proposed by Sir [Humphry] Davy. Fluoric acid forms salts by uniting with several bases. Five fluates have⟳ hitherto been found native; viz., the fluate of lime, or fluor-spar, the fluo-silicate of alumine, or topaz, the fluate of cerium, the double⟳ fluate of cerium and yttria, and the double⟳ fluate of soda and alumine, or cryolite. The four latter are very rare minerals, but the first is abundant. Potash unites with fluoric acid in two proportions, forming a fluate and a bifluate, the former of which consists of one atom and the latter of two atoms of acid united with one atom of the alkali. A neutral fluate of soda may be obtained directly from fluoric acid and carbonate of soda. It melts with more difficulty than glass; 100 parts of water, at 212° Fahrenheit, dissolve only 4.3 of it.”
