A) \[4\times {{10}^{-15}}\]
B) \[4\times {{10}^{-10}}\]
C) \[1\times {{10}^{-15}}\]
D) \[1\times {{10}^{-10}}\]
Correct Answer: A
Solution :
\[A{{B}_{2}}\] ⇌ \[\underset{1\times {{10}^{-5}}}{\mathop{{{A}^{+}}\,\,\,}}\,\,\,+\,\,\,\,\,\underset{2\times {{10}^{-5}}}{\mathop{2{{B}^{-}}}}\,\] \[{{K}_{sp}}=[1\times {{10}^{-5}}]\,\,{{[2\times {{10}^{-5}}]}^{2}}=4\times {{10}^{-15}}\]You need to login to perform this action.
