but using current concentrations rather than equilibrium concentrations. : The solution is (no precipitate). : The solution is saturated (equilibrium). : The solution is supersaturated (precipitation occurs). 2. Fractional Precipitation POGIL Answer Key Guide Q1: Defining Fractional Precipitation
8.5×10-17=(1.8×10-9 M)×[I−]8.5 cross 10 to the negative 17 power equals open paren 1.8 cross 10 to the negative 9 power M close paren cross open bracket I raised to the negative power close bracket
) are removed because they do not participate in the formation of the solid. fractional precipitation pogil answer key
[Cl−]remaining=Ksp of AgCl[Ag+]=1.8×10-103.46×10-6 M=5.2×10-5 Mopen bracket cap C l raised to the negative power close bracket sub remaining end-sub equals the fraction with numerator cap K sub s p end-sub of cap A g cap C l and denominator open bracket cap A g raised to the positive power close bracket end-fraction equals the fraction with numerator 1.8 cross 10 to the negative 10 power and denominator 3.46 cross 10 to the negative 6 power M end-fraction equals 5.2 cross 10 to the negative 5 power M
Phase 2: Calculating the Cation Concentration Needed to Start Precipitation : The solution is supersaturated (precipitation occurs)
POGIL activities are designed to build your mental model step-by-step. Do not jump straight to the math; answer the guiding questions about particle diagrams and trends first.
