Fractional precipitation is a technique used to separate ions from a solution by adding a reagent that forms a precipitate with one ion at a time. The ion that forms the compound (the one with the smallest Kspcap K sub s p end-sub ) will typically precipitate first. Understanding Fractional Precipitation When you have a solution containing multiple ions (like Cl−cap C l raised to the negative power I−cap I raised to the negative power Step 2: Calculate the Minimum Reagent Concentration for

To separate: Add CrO₄²⁻ until [Ba²⁺] is very low but before SrCrO₄ precipitates. fractional precipitation pogil answer key best
