SECTION POSTLABORATORY ASSIGNMENT 1. An "iodide/chloride/sulfate" unknown solution gave a yellow precipitate aqueous 3. The supernate did not react with Ba(NO32. A portion of the yellow precipitate olved in aqueous NH4OH. After centrifuging, the supernate was acidified with HNO3. which gave a white precipitate. State the anion(s) confirmed present and absent in the unknown solution Anion(s) present Anion(s) absent O- 2. An "iodide/chloride/sulfate" unknown solution gave no reaction with aqueous AgN However, the unknown solution produced a white precipitate with aqueous Ba(NO3)2. State the anion(s) confirmed present and absent in the unknown solution. Anion(s) absent Anion(s) present
