Precipitation begins when the exceeds the solubility product constant ((K_sp)). For a generic salt (A_mB_n): [ Q = [A^n+]^m [B^m-]^n ] When (Q > K_sp), precipitation occurs. The key to fractional precipitation is that the smaller the (K_sp), the lower the concentration of precipitating ion needed to start precipitation.
(or the one that requires the lowest concentration of the added reagent to reach its cap K sub s p end-sub ) will precipitate first. 2. Analytical Procedure for Separation
