We have a solution that contains 0.010 M Zn2+ ion and 0.010 M
Mn2+ ion. What concentration of S2- ion is required to precipitate
the maximum amount of ZnS without precipitating any MnS? K sp (ZnS)
= 1.1 x 10-21; Ksp (MnS) = 5.1 x 10-15 (
a) 0.0050 M
(b) 5.1 x 10-13 M
(c) 0.010 M
(d) 1.1 x 10-19 M
Answer is B
