l6 CHEMICAL GERMAN 



by affixing the word saure to the name of the substance acidified, 



which latter is sometimes abbreviated. 

 EXAMPLES : 



Chromsaure chromic acid 



Jodsaure iodic acid 



Borsaure boric acid 



Phosphorsaure phosphoric acid 



Arsensaure arsenic acid 



Osmiumsaure osmic acid 



Schwefelsaure sulphuric acid 



Zyansaure - cyanic acid 



Zyanursaure ." cyanuric acid 



Molybdansaure molybdic acid 



The names of acids ending in -ous are formed in German by 



adding the word saure to the name of the substance acidified, 



lengthened by the termination -igc or -ge, which then becomes 



an adjective. 



EXAMPLES: 



schweflige Saure sulphurous acid 



chlorige Saure chlorous acid 



phosphorige Saure phosphorous acid 



selenige Saure selenious acid 



Or the two words may be consolidated in one. 



EXAMPLES: 



Schwefligesaure 



Chlorigesaure 



Phosphorigesaure 



Selenigesaure 



It is more common at present to express the names of the 

 lower oxygen acids by using the two words separately. Such 

 terms as Salpetrigesaure are found mainly in older books. 



The following names will be readily understood as illustrating 

 the use of prefixes in the case of elements forming several 

 oxygen acids: 



unterchlorige SSure hypochlorous acid 



Uberchlorsaure perchloric acid 



unterphosphorige Saure hypophosphorous acid 



Ilbermangansaure permanganic acid 



Uberchromsaure perchromic acid 



The name of an anhydride is formed by affixing the word 

 anhydrid to the name of the acid. Thus:
