A) \[5.3\times {{10}^{12}}\]
B) \[~2.42\times {{10}^{8}}\]
C) \[2.66\times {{10}^{12}}\]
D) \[~4.5\times {{10}^{11}}\]
Correct Answer: A
Solution :
\[A{{g}_{2}}{{C}_{2}}{{O}_{4}}(s)\underset{2s}{\mathop{2A{{g}^{+}}(aq)}}\,+\underset{s}{\mathop{{{C}_{2}}O_{4}^{2-}(aq)}}\,\] \[{{K}_{sp}}={{[A{{g}^{+}}]}^{2}}[{{C}_{2}}{{O}_{4}}^{2-}]\] \[[A{{g}^{+}}]=2.2\times {{10}^{-4}}M\] \[\therefore \] \[{{K}_{SP}}={{(2.2\times {{10}^{-4}})}^{2}}(1.1\times {{10}^{-4}})\] \[=5.324\times {{10}^{-12}}\]You need to login to perform this action.
