An unknown solution gave a yellowish precipitate when silver nitrate was added. The precipitate did not appear to dissolve when aqueous ammonia was added, but when the supernatant that contained the ammonia was acidified with nitric acid, a white precipitate formed. When barium nitrate was added to the original supernatant, no reaction occurred. Use the words "present" or "absent" to summarize the results for each ion in the blanks below: chloride: iodide: sulfate: An unknown solution gave no reaction when silver nitrate was added. When barium nitrate was added, a white precipitate formed. Use the words "present" or "absent" to summarize the results for each ion in the blanks below: chloride: iodide: sulfate: Write the formulas for chloride, sulfate, and phosphate compounds formed with the following ions. barium ion chromium(III) ion ammonium ion tin(IV)ion
