Q74 Chemical Nomenclature of Berzelius. 
B. HALOID SALTS. 
Ist. Acid haloid salts.(71) 
An acid haloid salt is composed of a haloid salt, united to. the hy- 
dracid of its halogen radical; its composition will be sufficiently well 
expressed by the rmethad exhibited in the following examples. 
Acid auric chloruret. Chloride of gold and muriatic acid. 
Acid potassic fluoruret. Fluoride of potassium and hydrofluoric 
Acid ferrous cyanuret. acid. 
Acid ferric cyanuret. — 
2nd. Basic haloid salis.(72) 
The haloid salts combine with oxybases and occasionally with sul- 
phobases. ‘These compounds may be called oxybasic and sulphoba- 
sic salts. When these salts combine with oxybases, we may dis- 
pense with expressing the oxygen, and merely call them basic ha- 
loid salts. ‘Thus far we know of no basic salt, in which, to use an 
example, the ferrous chloruret is combined with the ferric oxide, or 
the ferric chloruret with the ferrous oxide, consequently the name of 
the chloruret expresses always the degree of oxidation of the oxy- 
base. But as one atom of a haloid salt may combine with one, two, 
three or more atoms of a metallic oxide of the same radical, the 
peculiar composition is expressed as in the following examples : 
Basic plumbic chloruret. Tribasic plumbic chloruret. 
Bibasic plumbic chloruret. Quadribasic plumbic chloruret. 
NOMENCLATURE OF THE DOUBLE SALTS, THOSE CONTAINING TWO 
BASES OR TWO ACIDS. 
In proportion as the elements of a compound increase in number, 
the difficulties of applying the principles of a systematic nomencla- 
(71) The literal translation would be ‘Ist, those with an excess of acid.” This 
conveys an erroneous idea and leads me to suppose that the French translator, has 
not done the author justice. I have substituted ‘acid haloid salts.” Reference is - 
here made to three divisions of these salts. Ist. Haloid salts, those salts formed by 
a halogen body with a less electro-negative body (chlorides, &c.) 2nd. Acid haloid 
salts, or haloid salts combined with acids. 3d. Basic haloid salts, or haloid salts 
combined with bases. Since these acid haloid salts contain the hydracid of the hal- 
ogen body which forms the salt, Turner proposes to cail them hydro-haloid salts. 
(See 4th Amer. Ed. p. 450). The name of Berzelius strikes me as most expressive.— 
Trans. 
(72) In the French “avec excés de base,” but changed for reasons analogous | to 
those given in the note under the head of the acid haloid salts. 
Turner proposes for these salts, the term oxyhaloid salts, leaving out the basic. 
Berzelius prefers to leave out ory, and call them basic haloid salts.— Trans.
