POGILs are notorious for being picky about sig figs. Ensure your calculations match the precision of the data given in the "Model" diagrams.

Fractional precipitation is a laboratory technique used to separate ions in a solution by adding a reagent that forms a precipitate with one or more of those ions. Because different salts have different solubilities (represented by the solubility product constant, ), they don't all precipitate at the same time. POGILs are notorious for being picky about sig figs
By carefully controlling the concentration of the precipitating agent, you can force the least soluble salt to drop out of the liquid while keeping the more soluble ions in the solution.

Pay attention to the stoichiometry. If one salt is XYcap X cap Y and the other is X2Ycap X sub 2 cap Y , you cannot compare Kspcap K sub s p end-sub
