Let x = solubility Ag2SO4, then
Ag2SO4 ==> 2Ag^+ + SO4^=
...x........2x......x.
........K2SO4 ==> 2K^+ + SO4^=
initial.0.30M.......0......0
equil.....0.......0.6.....0.30
Ksp = (Ag^+)^2(SO4^2-)
You know Ksp.'
(Ag^+) = 2x from Ag2SO4
(SO4^2-) = x from Ag2SO4 and 0.30M from K2SO4 so the total is x+0.30
Substitute into Ksp expression and solve for x.
The Ksp for silver sulfate (Ag2SO4) is 1.2 10-5. Calculate the solubility of silver sulfate in each of the following.
