A) \[12\times {{10}^{-23}}\]
B) \[12\times {{10}^{-21}}\]
C) \[3\times {{10}^{-19}}\]
D) \[3\times {{10}^{-22}}\]
Correct Answer: D
Solution :
\[\underset{S'}{\mathop{Al{{(OH)}_{3}}A{{l}^{+3}}}}\,\underset{0.2+3(S')\simeq 0.2}{\mathop{+3O{{H}^{-}}}}\,\] \[S'\times {{(0.2)}^{2}}={{k}_{sp}}=2.4\times {{10}^{-24}}\] \[(S')=3\times {{10}^{-22}}M\]You need to login to perform this action.
