A) between \[{{10}^{-8}}\]M, to \[{{10}^{-7}}\]M
B) between \[{{10}^{-7}}\]M to \[{{10}^{-8}}\]M
C) \[>{{10}^{-5}}M\]
D) \[<{{10}^{-8}}M\]
Correct Answer: C
Solution :
A salt is precipitated only when the product of ionic concentration is more than its solubility product. \[{{K}_{sp}}=1\times {{10}^{-8}}\] \[[{{A}^{+}}]={{10}^{-3}}M\] \[[{{B}^{-1}}]=\frac{1\times {{10}^{-8}}}{{{10}^{-3}}}={{10}^{-5}}M\] So, AB will be precipitated only when the concentration of \[[{{B}^{-}}]\]is more than \[{{10}^{-5}}\]M.You need to login to perform this action.
