Hg₂Cl₂ has the smallest Ksp (1.3 × 10⁻¹⁸), so it will precipitate first.
Ksp = [Ag⁺][Cl⁻] = 1.8 × 10⁻¹⁰ [Cl⁻] = (1.8×10⁻¹⁰) / (0.01) = 1.8 × 10⁻⁸ M fractional precipitation pogil answer key
[Ag+]=1.8×10-100.10 M=1.8×10-9 Mopen bracket Ag raised to the positive power close bracket equals the fraction with numerator 1.8 cross 10 to the negative 10 power and denominator 0.10 M end-fraction equals 1.8 cross 10 to the negative 9 power M As you add Ag+Ag raised to the positive power to the beaker, the concentration climbs. It hits first, causing to form a solid. will not begin to precipitate until the Ag+Ag raised to the positive power concentration reaches Phase 3: Determining Efficiency of the Separation Hg₂Cl₂ has the smallest Ksp (1
Ksp=[Ag+][Cl−]cap K sub s p end-sub equals open bracket Ag raised to the positive power close bracket open bracket Cl raised to the negative power close bracket will not begin to precipitate until the Ag+Ag
The answer is .
AP Chemistry and college-level general chemistry exams rarely ask plug-and-chug questions. They test the conceptual "why" found in POGIL critical thinking questions.
