5. Based on your reading about qualitative analysis and your knowledge of the solubility rules, consider the following scenario. An unknown mixture of ions may contain the following ions: Ct, I, CO,?, SO?,, PO,², NO,. The following tests are performed on the unknown solution and these are the results: i) AGNO, is added to the mixture and no precipitate forms. ii) BaClz is added to the mixture and no precipitate forms. Based on the results (i) and (ii), answer the following: a) Which ions (if any) are definitely identified? vThere are no ions that are identified. dafinitaly Which ions (if any) are definitely nọt in the unknown mixture? F are detinitely in the unknown mixture. not Which ions (if any) would require further tests in order to determine their presence in the unknownm mixture? NO5 and PO would require further tests in order to determine their presence in the vuknown mixture.

5. Based on your reading about qualitative analysis and your knowledge of the solubility
rules, consider the following scenario. An unknown mixture of ions may contain the
following ions: Cl, I', CO,?, SO?, PO,², NO3. The following tests are performed
on the unknown solution and these are the results:
i) AGNO3 is added to the mixture and no precipitate forms.
ii) BaClz is added to the mixture and no precipitate forms.
Based on the results (i) and (ii), answer the following:
a) Which ions (if any) are definitely identified?
vThere are no ions that are definitely
identified.
by Which ions (if any) are definitely not in the unknown mixture?
CO5,ľ, CT, und SO4F are detinitely not
in the unknown mixture.
Which ions (if any) would require further tests in order to determine their presence
in the unknown mixture?
NO and PO would require further tusts
in order to determine their presence
in the vuknown mixture.
