The  test  for  iodids  in  bromids  has  been  made  more  sensitive  and 
reliable  for  general  use  by  the  method  of  agitating  with  a  small 
volume  of  chloroform  while  adding  diluted  chlorin  water  drop  by 
drop.  The  pale  rose  to  faint  violet  coloration  of  1  c.c.  of  chloroform 
produced  by  traces  of  iodin  is  readily  and  accurately  distinguished 
before  any  blue  with  starch  paste  might  be  noted.  The  presence 
of  005  milligrammes  of  KI  will  impart  a  faint  violet  color  to 
chloroform.  This  immiscible  solvent  chloroform  is  not  so  readily 
decolorized  through  an  excess  of  chlorin  water  as  an  aqueous  solu- 
tion of  iodized  starch.  Starch  solution  in  the  hands  of  the  inexperi- 
enced, careless  as  to  its  freshness  and  proper  preparation,  is  a  very 
unreliable  reagent  for  traces  of  iodin.  While  the  presence  of  sulfates 
and  chlorids  may  be  ignored  in  the  alkali  salts,  we  must  restrict 
them  in  such  zinc  salts  as  the  bromid,  iodid  and  valerate,  which  are 
given  in  fair-sized  doses  extending  at  times  over  greater  periods.  I 
have  been  assured  from  very  reliable  sources  that  zinc  dross  (waste 
from  galvanizing  iron)  is  largely  used  in  the  preparation  of  the 
various  medicinal  zinc  salts,  while  the  best  grades  of  zinc  oxid 
(98-5  to  99  per  cent.)  are  demanded  by  the  paint  manufacturers. 
The  test  limiting  the  chlorids  in  bromids  and  iodids  of  zinc  to  o-i 
per  cent,  is  based  on  the  fact  that  when  a  solution  of  lead  bromid  or 
iodid  in  acetic  acid  is  evaporated,  the  two  halogens  are  volatilized, 
leaving  a  chlorid  behind  which  is  identified  in  the  usual  manner. 
Bromin. — Various  samples  of  German  bromin  assayed  99  per 
cent,  while  that  of  Michigan  origin  was  98-5  per  cent.  Bromin  from 
Western  Pennsylvania  and  Ohio  contained  from  6  to  12  per  cent,  of 
chlorin.
