Question
Some chemists at ISRO wished to prepare a saturated solution of a silver compound and they wanted it to have the highest concentration of silver ion possible. Which of the following compounds would they use ?
Given:-
Ksp (AgCl) = 1.8 × 10-10.
Ksp (AgCl) = 1.8 × 10-10.
Ksp(AgBr) = 5.0 × 10-13,
Ksp (Ag2CrO4) = 2.4 ×10-12 [use
= 0.84]
Ksp (Ag2CrO4) = 2.4 ×10-12 [use
= 0.84] Options
A.AgCl
B.AgBr
C.Ag2CrO4
D.All of these
Solution
Find the [Ag+] in all the saturated solutions.
[Ag+]in AgCl =
M;
[Ag+]in AgBr =
M
[Ag+]in AgrCrO4 = 2
⇒ [Ag+] is maximum in saturated solution of Ag2CrO4.
[Ag+]in AgCl =
M;[Ag+]in AgBr =
M[Ag+]in AgrCrO4 = 2
⇒ [Ag+] is maximum in saturated solution of Ag2CrO4.
