summary:
For solving this type of problem, you first know that Na2SO4 is strong electrolytes. So it will dissociate completely. This means the concentration of sulfate ion is 0.010M in saturated solution of PbSO4 containing 0.010 M Na2SO4 due to dissociation of 0.010M of Na2SO4.
So initial concentration of Sulfate in saturated solution of PbSO4 is 0.010M while initial concentration of lead in PbSO4 saturated solution is 0 M.
Since PbSO4 is weak electrolyte . So it will not dissociate completely. Let s be the molar solubility of PbSO4. So we write expression of Ksp for PbSO4 to calculate value of s.
Remember:
Molar solubility s is very small compared to 0.010M
So 0.010+s = 0.010M
So after calculation,
Answer = 6.3 × 10 ^-5 M
