Step 2: Determine the Required Cation Concentration for Each Cation
A common "critical thinking" question in these POGILs asks how much of the first ion remains when the second begins to precipitate. required for the precipitate to form. back into the cap K sub s p end-sub expression of the precipitate. Solve for the concentration of the first cation. fractional precipitation pogil answer key
A common misconception is that the compound with the smallest Kspcap K sub s p end-sub Step 2: Determine the Required Cation Concentration for
This requires careful application of equilibrium principles. Since AgI has already been precipitating, the solution remains saturated with respect to AgI at this point. Using the Kₛₚ expression: fractional precipitation pogil answer key
