A) \[{{10}^{-4}}M\]
B) \[{{10}^{-7}}M\]
C) \[{{10}^{-6}}M\]
D) \[{{10}^{-5}}M\]
Correct Answer: D
Solution :
For binary salt AB, \[{{K}_{sp}}={{s}^{2}}=[A][B]\] \[\therefore \] \[{{10}^{-8}}={{10}^{-3}}\times [B]\] \[\therefore \] \[[B]={{10}^{-5}}M\] Hence, when [B] will be more than \[{{10}^{-5}}\] M, the salt will be precipitated.You need to login to perform this action.
