Question

Consider a 5 solution problem in which the 5 solutions are 2.0 M HNO3, H2O, 0.2 M NaI, 1.0 M Pb(CH3COO)2, and 0.1 M K2SO4. Create a table of predictions which lists the anticipated results expected when each solution is mixed.
Enter NR when no reaction is predicted. Consider a 5 solution problem in which the 5 solutions are 2.0 M HNO3, H2O, 0.2 M NaI, 1.0 M Pb(CH3COO)2, and 0.1 M K2SO4. Create a table of predictions which lists the anticipated results expected when each solution is mixed.

Explanation / Answer

Reaction of solutions

Solution                              2.0 M HNO3       H2O         0.2 M NaI        1.0 M Pb(CH3COO)2       0.1 M K2SO4

2.0 M HNO3                               NR             ionize       HI formed       Pb(NO3)2+CH3COOH       H2SO4+KNO3

H2O                                         ionize              NR              NR                           NR                              NR  

0.2 M NaI                             HI formed           NR              NR                      PbI2(ppt)                    KI+Na2SO4            

1.0 M Pb(CH3COO)2              soluble            NR         PbI2(ppt)                      NR                         PbSO4(ppt)

0.1 M K2SO4                           soluble            NR       KI+Na2SO4             PbSO4(ppt)                        NR

In the above cases, ppt is formed PbSO4, PbI2. Rest all showed either soluble products or no reaction.
