expression to find the concentration of the added reagent needed to start precipitating each ion.

Before diving into answer keys, let's recap the science. Fractional precipitation is a technique used to separate two or more ions (e.g., Cl⁻, I⁻, or Ba²⁺, Ca²⁺) from an aqueous solution. It relies on adding a precipitating reagent (like AgNO₃ or Na₂SO₄) drop by drop. The ion that forms the least soluble compound (lowest Ksp) will precipitate first. fractional precipitation pogil answer key best

The salt with the smaller (K_sp) requires a lower concentration of the common ion to reach saturation. This is the cardinal rule of fractional precipitation. fractional precipitation pogil answer key best
