Gooch crucible . = 13-7418 



+ substance . =13-9567 -2151 g. taken for analysis. 



(N.B. — Ash is hygroscopic, as original total 

 weight was -2012 g.) 



Dry at 134°. . =139071 



Extract hot water =13-745r) 

 „ HCl . =13-7420 



•1653 g. dry ash. 



•0498 g. loss = moisture 23-15 per cent. 



. ■ . ash almost completely soluble in water 

 and quite so in dil. HCl. 



Added HCl to the extracts and evaporated to dryness in silica basin. 



Basin . . . =57-4761 



+ substance . =57-6427 =-1666 g. chlorides. 



Transferred to beaker, added acetic acid, ammonium oxalate. Filtered, washed, 

 ignited precipitate.
