Problem-Sodium sulfate is slowly added to a solution containing 0.0500 M Ca2 (aq) and 0.0280 M Ag (aq).
1) What will be the concentration of Ca2 (aq) when Ag2SO4(s) begins to precipitate?
[Ca2+]=_________M
2) What percentage of the Ca2 (aq) can be separated from the Ag (aq) by selective precipitation?
Solve the above problem and provide steps with explanation
