-5 When 15.0 mL of a 4.09 x 10-4 M manganese(II) nitrate solution is combined with 15.0 mL of a 6.80 x 10° M potassium sulfide solution does a precipitate form? ( Ksp (MnS) = 5.1 × 10-¹5) Yes, the precipitate forms. No, the precipitate doesn't form. For these conditions the Reaction Quotient, Q, is equal to
Solid calcium acetate is slowly added to 50.0 mL of a 0.0437 M potassium sulfide solution. The concentration of calcium ion required to just initiate precipitation is M. (Assume that Ksp (CaS) = 8.0 × 10–6 .)
