NOMENCLATURE OF THE ACID AND OF THE BASIC SALTS. 
A. AMPHIDE SALTS. 
The salts which contain an excess of acid, are generally known as 
acid or super salts. By prefixing, to the name of the salt, the par- 
ticle which expresses the number of proportionals of acid contained 
in the salt, the relation of acid to base in the neutral salt being called 
unity, the fact that the salt is acid and the degree of its acidity, are 
expressed at the same time. For example we say, 
Ammoniacal sesquicarbonate. 
Sodic bisulphate. 
Potassic quadroxalate. 
' The amphide salts containing an excess of base, are called basic 
or sub salts. Subphosphate, subsulphate express compounds of phos- 
phoric and of sulphuric acid with a base, in which the latter is in ex- 
cess. To express the degree of this excess, we use the same par- 
ticles, which were applied in the cases of the acid salts. The fol- 
lowing examples will suffice to show the method of applying these 
particles. 
Sesquicalcic(70) subphosphate. 
Bicupric subacetate. 
Trialuminic subsulphate. 
Quadriplumbic subnitrate. 
Sexplumbic subnitrate. 
The nomenclature thus shows whether the proportion of base is a 
multiple by 13 by 2, 3, 4 or 6, of that required to form a neu- 
tral salt. 
It is easily seen that the same method applies to the other am- 
phide salts. 
(70) Since the prepositions sesqui, bi, &c. are prefixed to the base in this case and 
were prefixed to the acid in the acid salts, it seems superfluous to use the term sub 
before the name of the acid; thus trialuminie sulphate expresses three proportions 
of the base to one of the acid, while sodie bisulphate would express two proportions 
of the acid to one of the base.— Trams.
