A)Sodium sulfate is slowly added to a solution containing 0.0500 M Ca2 (aq) and 0.0240 M Ag (aq). What will be the concentration of Ca2 (aq) when Ag2SO4(s) begins to precipitate? Solubility-product constants, Ksp, can be found here. B)What percentage of the Ca2 (aq) can be precipitated from the Ag (aq) by selective precipitation?
