Sodic bisulpbate 8207^0:^. Potassic bichromate ... Ci\O^K^. An acid salt is one in which the displaceable hydrogen of the acid is only partially exchanged for a metal or positive compound radical. The following examples illustrate the constitution and nomen- clature of these salts:— Acid. Sulphm’ic acid ... SO^.£r2 Carbonic acid ... Phosphoric acid... POjZTg ■ Acid salt. Hydrie sodic sulphate ^OJJNa. Hydric potassic carbonate.. CO^HK. Hydrie disodic phosphate... TO^HNa,^. Dihydric sodic phosphate... PO^^AT^iVh. . Microcosmic salt (Hydrie ammonic sodic phosiDhate.) Acid salts are produced almost exclusively from polybasic acids. When the number of bonds* of the metal or compound positive radical contained in a salt exceeds the number of atoms of displace- able hydrogen in the acid, the compound is usually termed a basic salt—as, for instance, - Acid. Carbonic acid ... Sidphuric acid... Basic salt.

This will be seen from the arrangement of their atoms given under the different metals entering into their composition. The nomenclature of organic bodies is founded upon the same principles as that of inorganic compounds ; but its discus- sion could not be conveniently introduced here. * For an explanation of this term see Chap. III. p. 18.](https://iiif.wellcomecollection.org/image/b28127791_0029.jp2/full/800%2C/0/default.jpg)
