A) \[\sqrt{2}x\]
B) \[2{{x}^{2}}\]
C) \[4{{x}^{3}}\]
D) \[{{x}^{2}}\]
Correct Answer: C
Solution :
\[\underset{x}{\mathop{Ca{{F}_{2}}}}\,\rightleftharpoons \underset{x}{\mathop{C{{a}^{2+}}}}\,+\underset{2x}{\mathop{2{{F}^{-}}}}\,\] \[{{K}_{sp}}=[C{{a}^{2+}}]{{[2{{F}^{-}}]}^{2}}\] \[=(x){{(2x)}^{2}}=4{{x}^{3}}\]You need to login to perform this action.
