n this experiment, you will be given a number of tests that you can perform and you will need to figure out which test is useful for the determining the presence of which ion.  An example is provided below.  One test that can be used to determine some ions is to add a solution of Pb(NO3)2 (aq) to an aqueous solution of your unknown.  In this example, Pb(NO3)2 (aq) is added to 4 different solutions and the following results are recorded: When Pb(NO3)2 (aq)  is added to an aqueous solution of NaCl, a yellow precipitate forms immediately. When Pb(NO3)2 (aq)  is added to an aqueous solution of NaNO3, no change is observed.  When Pb(NO3)2 (aq)  is added to an aqueous solution of KCl, a yellow precipitate forms immediately. When Pb(NO3)2 (aq)  is added to an aqueous solution of KNO3, no change occurs.   Based on these results, select all of the following that are consistent with this data using the solubility table when necessary.

In this experiment, you will be given a number of tests that you can perform and you will need to figure out which test is useful for the determining the presence of which ion.  An example is provided below.  One test that can be used to determine some ions is to add a solution of Pb(NO3)2 (aq) to an aqueous solution of your unknown. 

In this example, Pb(NO3)2 (aq) is added to 4 different solutions and the following results are recorded:

  • When Pb(NO3)2 (aq)  is added to an aqueous solution of NaCl, a yellow precipitate forms immediately.
  • When Pb(NO3)2 (aq)  is added to an aqueous solution of NaNO3, no change is observed. 
  • When Pb(NO3)2 (aq)  is added to an aqueous solution of KCl, a yellow precipitate forms immediately.
  • When Pb(NO3)2 (aq)  is added to an aqueous solution of KNO3, no change occurs.  

Based on these results, select all of the following that are consistent with this data using the solubility table when necessary.

Group of answer choices
Addition of Pb(NO3)2 to a solution containing chloride ions will result in a precipitate.
Addition of Pb(NO3)2 to a solution containing potassium ions will result in a precipitate.
Addition of Pb(NO3)2 to a solution containing sodium ions will result in a precipitate.
Addition of Pb(NO3)2 would be a good test for chloride ions.
Addition of Pb(NO3)2 would be a good test for sodium ions.
Addition of Pb(NO3)2 would be a good test for potassium ions.
The net ionic equation that explains what is happening in this test is:   NO3- (aq) + Na+(aq) -->  NaNO3(s)
The net ionic equation that explains what is happening in this test is:  Pb2+(aq) + 2Na+(aq) -->  PbNa(s)
The net ionic equation that explains what is happening in this test is:   Pb2+ (aq) + 2Cl-(aq) -->  PbCl2(s)
The net ionic equation that explains what is happening in this test is:   Pb2+ (aq) +2 NO3-(aq) -->  Pb(NO3)2(s)
