THE SYNTHESIS OF ARGENTIC CHLORIDE. 



6l 



A few inessential changes in the mode of precipitation were occa- 

 sionally introduced. In Experiments 75, 76, and 79 both solutions were 

 only about tenth normal, and the number of washings was diminished ; 

 in R. 1 the argentic nitrate was very dilute, but the hydrochloric acid 

 was somewhat concentrated. 



As has been said, the tentative experiments were all classed 

 together in a preliminary series, given immediately below. The table 

 explains itself, for the most part, except perhaps the second column. 

 This defines in the first place the designation of the silver, next the 

 nature of the containing vessel on which it was fused, and last the 

 atmosphere surrounding the metal during fusion. The word " blast " 

 signifies that the sample thus qualified was fused in a blast-flame of 

 illuminating gas and air, delivered from a clean nozzle, and that the 

 resulting mass was cooled in the reducing flame.
