Fractional Precipitation Pogil Answer Key - Best

, the less soluble the compound is, and the more readily it will precipitate out of a solution. The Ion Product ( Kspcap K sub s p end-sub The reaction quotient (

To effectively answer the POGIL activity questions, you must grasp these core concepts: 1. Solubility Product Constant ( Kspcap K sub s p end-sub Kspcap K sub s p end-sub , the less soluble the compound is, and

Cu(aq)2++CO3(aq)2−⇌CuCO3(s)(Ksp is relatively small)Cu sub open paren a q close paren end-sub raised to the 2 plus power plus CO sub 3 open paren a q close paren end-sub raised to the 2 minus power is in equilibrium with CuCO sub 3 open paren s close paren end-sub space open paren cap K sub s p end-sub is relatively small close paren required for the second ion's precipitation to solve

When two or more ions form insoluble salts with the same added reagent (e.g., Ag⁺ and Pb²⁺ with Cl⁻), the ion with the smaller (K_sp) (less soluble) precipitates first as the reagent concentration is gradually increased.

required for the second ion's precipitation to solve for the remaining concentration of the first cation. Success Criterion
