Solid Na2SO4 is added slowly to a solution that is 0.10 M in PbfNO,), and 0.10 M in Ba(NO})2. In what order will solid PbSO4 and BaS04 form? Calculate the percentage of B.r * that precipitates just before PbSO4 begins to precipitate.

Interpretation Introduction

To determine: Solid Na2SO4 is added slowly to a solution that 0.01M in Pb(NO3)2and 0.01M in Ba(NO3)2. In what order will solid PbSO4and BaSO4 form.

Determine the percentage of Ba2+ that precipitates just before PbSO4 begins to precipitate.


First find the concentration SO42 for equilibrium of PbSO4and BaSO4 in the solution.


Concentration of Pb(NO3)2 in the solution is 0.10M. Due to this initial concentration Pb2+(aq)=0.10M.

Now let x M of NaSO4 is added before precipitation of PbSO4(S).

PbSO4(S) Pb(aq) SO42
Initial concentration due to PbS O 4 ( S ) Solid 0.10 0
Change in concentration due to addition of N a 2 S O 4 Solid 0 x
Final concentration 0.10 x

KSP=[Pb2+][SO42]KSP of PbSO4=1.8×107[Pb2+]=0.10M[SO42]=xM1.8×108=(0.10)×(x)x=1.8×108M

Minimum concentration of SO42 in solution to start precipitation of PbSO4=1.8×107M.

Similarly find out minimum concentration of SO42 to start precipitation of BaSO4.


Concentration of Ba(NO3)2 in the solution is 0.10M due to this there are initial concentration of Ba2+(aq) and it is equal to 0.10M

Now let x M of NaSO4 is added just before to start the precipitation of BaSO4(S).

BaSO4(S) Ba(aq) SO4(aq)
Initial concentration due to Ba ( N O 3 ) 2 Solid 0
