Question
Solubility product of a salt AB is 1 × 10-8 in a solution in which th concentration of A+ ions is 10-3 M. The salt will precipitate when the concentration of B- ions is kept
Options
A.between 10-8 M to 10-7 M
B.between 10-7 M to 10-8 M
C.> 10-5 M
D.< 10-8 M
Solution
AB ⇋ A+ + B-
Ksp - [A+][B-]
Salt will precipiteate of ionic conc. > Ksp
[A+][B-] > 1 × 10-8
(1 × 10-3)[B-] > 1 × 10-8
[B-] >
or 1 × 10-5
Ksp - [A+][B-]
Salt will precipiteate of ionic conc. > Ksp
