Oxygen acids

The names for the common oxygen acids of the halogens, sulfur, nitrogen, phosphorus, and arsenic are considered to be so well established that attempts to alter them to fit a more systematic pattern have not met with favor. The preferred names of these acids and their salts are listed [Pg.278]

It will be recalled that the designations, hypo-. . -ous, -ous, -ic, and per. , ic (as illustrated above with the oxy-acids of chlorine) refer to a series of acids in which the oxidation number of the central atom progresses in units of 2. Hypophosphoric acid, H4P2O6 (p. 255) is a special case in which the formal oxidation number of phosphorus is between that in the -ous acid and that in the -ic acid. [Pg.278]

In some cases, a single oxidation state of a given nonmetallic element may form more than one oxygen acid or derivatives of more than one oxy-acid, Pentapositive phosphorus has been shown, for example, to yield [Pg.278]
