_Note._--All these salts were unknown to the ancients; and even those
chemists who are most versant in modern discoveries, are yet at a lose
whether the greater part of the salts produced by the oxygenated acetic
radical belong properly to the class of acetites, or to that of
acetats.--A.
SECT. XXXIV.--_Observations upon Acetic Acid, and its Combinations._
We have given to radical vinegar the name of acetic acid, from supposing
that it consists of the same radical with that of the acetous acid, but
more highly saturated with oxygen. According to this idea, acetic acid
is the highest degree of oxygenation of which the hydro-carbonous
radical is susceptible; but, although this circumstance be extremely
probable, it requires to be confirmed by farther, and more decisive
experiments, before it be adopted as an absolute chemical truth. We
procure this acid as follows: Upon three parts acetite of potash or of
copper, pour one part of concentrated sulphuric acid, and, by
distillation, a very highly concentrated vinegar is obtained, which we
call acetic acid, formerly named radical vinegar. It is not hitherto
rigorously proved that this acid is more highly oxygenated than the
acetous acid, nor that the difference between them may not consist in a
different proportion between the elements of the radical or base.
