Separation and Detection of Silver
Place 10 drops of the original solution to be analyzed in a small test tube and add five drops of distilled water and two drops of 6M HCl. Stire well, centrifuge. Wash the preciptate with 10 drops of distilled water, centrifuge, and add the washing to the supernatant. Dissolve the precipitate in four drops of 6M NH3, then add 6M HNO3 to the ammoniacal solution until it becomes acidic to litmus. A curdy white precipitate of AgCl confims the presence of Ag+ ions.
In the above procedure, when listing the reagent, are all the various solutions added to the original solutions reagents or is just the original 6M HCl the only reagent? What exactly are/is the reagent(s) for the above procedure?
