Fractional Precipitation Pogil Answer Key Best !link! -
Once you've established which compound precipitates first, the next step is quantitative. You will use Ksp values to calculate the exact concentration of the added reagent (e.g., [Ag⁺]) needed to just start the precipitation of each compound. This is the point where Q = Ksp.
A solution contains 0.1 M Ag+ and 0.1 M Na+ ions. If 0.1 M SO42- is added to the solution, which ion will precipitate first?
: Calculate the concentration of the added reagent just before the ion begins to precipitate. Evaluate Completeness fractional precipitation pogil answer key best

Fractional Precipitation: Separating Cations in Aqueous Mixtures
: The solution is saturated. This is the exact point where precipitation is about to begin.
A solution contains 0.010 M Cl⁻ and 0.010 M I⁻. Solid AgNO₃ is added dropwise. Using the (K_sp) values below, calculate the [Ag⁺] required to begin precipitation of each salt. Which precipitates first?
