The bottle shall be sealed with a rubber stopper and the reagent bottle and contents shaken until the solid material is dissolved
21、. To this solution 1.0 gm. of lead thiocyanate, 1.0 gm. of antimony sulfide and 1.0 gm. of lead azide shall be added. The bottle shall again be stoppered and the reagent bottle and contents vigorously shaken for several minutes, and then allowed to stand overnight. Portions of the saturated solution
22、 shall be filtered before using. Solution Number 2 - To approximately 400 ml. of distilled wter, in a one-half liter amber glass reagent 1.0 gm. of lead thiocyanate, 1.0 gm. of antimony sulfide and 1.0 gm. of lead azide shall be added.
