zu erklaren. Die Vermutung, daB molekulare Additionen 

 gebildet warden, findet keine geniigende Bestatigung. Kin 

 Molekiil Kaliumjodid verbindet sich mit zwei Atomen Jod zu 

 Kaliumtrijodid, welches sehr unbestandig ist und durch 

 Verdiinnen seiner waBrigen Losung wieder in Jodkalium und 

 freies Jod zersetzt wird. Das Antimonchloriir ist ein fester 

 Korper, welcher, durch Einwirkung von Chlor, in das flussige 

 und leicht fliichtige Pentachlorid verwandelt wird. 



DIE NOMENKLATUR DER SALZE. 

 The names of Oxygen salts may be formed in two different 

 ways. 



1. The name of the acid becomes an adjective and, deprived 

 of its umlaut, precedes the name of the metal. 



EXAMPLES: 



schwef elsaures Kalzium ................. calcium sulphate 



phosphorsaures Magnesium .............. magnesium phosphate 



kohlensaures Natrium ................... sodium carbonate 



salpetersaures Silber .................... silver nitrate 



unterchloriges saures Kalium ............ potassium hypochlorite 



chlorsaures Barium ..................... barium chlorate 



The English names sulphate of magnesia, carbonate of lime, 

 nitrate of strontia, etc., corresponding to the earlier theories of 

 the constitution of salts, had their counterpart in German and 

 we find in the older German works (and frequently in the 

 dealers' price lists and market quotations of the present time) 

 the expressions schwefelsanre Magnesia, kohlensaurer Kalk, 

 saltpetersaurer Strontian, salpetrigsanres Natron, schwefelsaure 

 Toner de. 



Acid salts are named by adding the adjective saner to the name 

 of the salt. 



EXAMPLES: 



saures kohlensaures Natrium ............ acid sodium carbonate 



saures phosphorsaures Kalzium ......... acid calcium phosphate 



2. Recent German authors incline more towards the Latin 

 names, the anglicized forms of which are so familiar to chemists 

 that their use in German will be readily understood from the 

 following examples:
