Thus the chlorine oxyacids enumerated above form salts named respectively hypochlorites, chlorites, chlorates and perchlorates.
nitrous oxide, N 2 0, nitric oxide, NO, nitrogen trioxide, N203, nitrogen peroxide, N02, and nitrogen pentoxide, N205, whilst three oxyacids of nitrogen are known: hyponitrous acid, H2N202, nitrous acid, HN02, and nitric acid, HNO 3 (q.v.).
difference between non-metallic and metallic hydroxides; the former are invariably acids (oxyacids), the latter are more usually basic, although acidic metallic oxides yield acidic hydroxides.
The unsaturated acids also received much attention, and he discovered the internal anhydrides of oxyacids, termed lactones.
If more than two be known, the one inferior in oxygen content has the prefix hypo- and the termination -ous, and the one superior in oxygen content has the prefix per- and the termination -ic. This is illustrated in the four oxyacids of chlorine, HC10, HC10 2, HC10 3, HC10 4, which have the names hypochlorous, chlorous, chloric and perchloric acids.
