A) \[{{s}_{0}}>{{s}_{1}}>{{s}_{2}}>{{s}_{3}}\]
B) \[{{s}_{0}}>{{s}_{2}}>{{s}_{1}}>{{s}_{3}}\]
C) \[{{s}_{0}}>{{s}_{2}}>{{s}_{3}}>{{s}_{1}}\]
D) \[{{s}_{0}}>{{s}_{1}}={{s}_{2}}>{{s}_{3}}\]
Correct Answer: B
Solution :
\[{{s}_{0}}=\sqrt{{{K}_{sp}};}\,{{s}_{1}}={{K}_{sp}}/0.02M;\,{{s}_{2}}={{K}_{sp}}/0.01\,M;\]\[{{s}_{3}}={{K}_{sp}}/0.05M\]Obviously \[{{s}_{0}}>{{s}_{2}}>{{s}_{1}}>{{s}_{3}}\]
