Key 2021 — Fractional Precipitation Pogil Answer

Fractional precipitation occurs when two or more ions in a homogeneous solution are separated by adding a single reagent that forms a precipitate with both ions. Because different compounds have different solubility product constants ( Kspcap K sub s p end-sub

When a precipitating agent is added dropwise to a solution containing multiple types of metal cations, the ion that requires the lowest concentration of the added reagent to exceed its solubility product equilibrium will drop out of the solution first.
