typically precipitates first because it requires a lower concentration of carbonate ions to turn into a solid. 3. The Separation: One Stays, One Goes : Effective separation is generally considered possible if

A smaller Ksp value indicates lower solubility. : There is no change in cation concentration

: There is no change in cation concentration initially because the cap Q sub s p end-sub (ion product) has not yet exceeded the cap K sub s p end-sub Order of Precipitation : The substance with the cap K sub s p end-sub precipitates first.

Without spoiling a specific answer key, here’s the deep conceptual structure common to all fractional precipitation POGILs:

BaSO4 (s) → Ba2+ (aq) + SO42- (aq) CaSO4 (s) → Ca2+ (aq) + SO42- (aq)
