A) \[4{{s}^{3}}\]
B) \[8{{s}^{3}}\]
C) \[4{{s}^{2}}\]
D) \[{{s}^{2}}\]
Correct Answer: A
Solution :
\[A{{X}_{2}}\underset{s}{\mathop{{{A}^{2+}}}}\,+\underset{2s}{\mathop{2{{X}^{-}}}}\,\] \[{{K}_{Sp}}=[{{A}^{2+}}]{{[{{X}^{-}}]}^{2}}\] \[{{K}_{Sp}}=(s){{(2s)}^{2}}\] \[{{K}_{Sp}}=(s)(4{{s}^{2}})\] \[{{K}_{Sp}}=4{{s}^{3}}\]You need to login to perform this action.
