The  absence  of  barium  from  strontium  salts  is  best  determined, 
according  to  Jungfleisch,  by  the  test  recommended  by  Liideking, 
by  adding  to  the  solution  of  the  salt  a  few  drops  of  a  saturated 
solution  of  neutral  potassium  chromate  and  of  acetic  acid,  and 
heating  ;  in  the  presence  of  barium  a  precipitate  of  barium 
chromate  will  make  its  appearance  in  a  few  minutes.  In  the  place 
of  the  neutral  chromate,  a  solution  of  potassium  bichromate  may  be 
used  together  with  sodium  acetate,  the  mixture  to  be  heated. —

Action  of  Sodium  Hypobromite  upon  Glass. — The  solution  of  sodium 
hypobromite  used  for  the  estimation  of  irea  is  recommended  to 
be  preserved  in  yellow  or  red  bottles.  After  keeping  such  a 
solution  in  a  red  bottle,  Deniges  observed  it  to  have  a  red 
instead  of  the  proper  yellow  color,  and  ascertained  this 
change  to  have  been  due  to  a  small  quantity  of  sodium  per- 
manganate formed  by  the  action  of  the  hypobromite  upon  the 
manganese  present  in  the  glass;  but  this  coloration  did  not  notably 
affect  the  solution  so  as  to  render  it  unfit  for  the  estimation  of 
urea. 
Solution  of  Chlorinated  Soda—  Herison  and  Lefort  propose  to 
prepare  this  solution  from  chlorinated  lime  by  decomposing  it  with 
sodium  sulphate  in  place  of  the  carbonate,  otherwise  following  the 
usual  process  of  precipitation  and  decantation  of  the  clear  liquid. 
Such  a  solution  has  the  advantage  of  being  neutral,  instead  of 
having  an  alkaline  reaction. 
Solution  of  A?itimonious  Chloride  in  Sodium  Chloride. — On  treat- 
ing an  excess  of  antimonious  oxide  with  strong  hydrochloric  acid 
in  the  cold,  a  saturated  solution  of  antimonious  chloride  in  free  acid 
is  obtained.  H.  Causse  (Comp.  rend.,  cxiii,  1042)  saturated  this 
acid  liquid  with  sodium  chloride,  and  observed  that  a  considerable 
amount  of  sodium  carbonate  may  be  added  to  the  solution  without 
causing  a  precipitate.  By  titration  with  soda  it  was  determined 
that  the  total  amount  of  free  HC1  may  thus  be  neutralized,  with  the 
result  that  antimonious  chloride  remains  dissolved  in  an  aqueous 
solution  of  sodium  chloride.
