Amount  of  Chloride  of  Zinc  [anhydrous)  contained  in  100 
parts  of  solution  of  different  densities. 
A  known  weight  of  pure  zinc  was  dissolved  in  hydrochloric 
acid,  avoiding  excess.  The  solution  evaporated  to  the  highest 
density,  given  in  the  table,  and  diluted  from  that  point. 
The  densities  "marked  *  were  found  by  experiment;  the  in- 
termediate ones  were  calculated.
