Condensed Types, Valency and Developed Formulas
Williamson  had related monobasic acids to the water type; they were represented as water in which one equivalent of hydrogen has been replaced by a certain group of elements, by an acid radical. Thus, nitric acid was water in which an equivalent of hydrogen has been replaced by the nitryl group, NO2. Acetic acid is water in which an equivalent of hydrogen has been replaced by the acetyl group C2H3O. Such substitution involves the replacement of one of the two equivalents of hydrogen contained in water. The other can, in turn, be replaced by an equivalent of a metal such as potassium, sodium or silver; salts are formed in this way.
