• # question_answer 16)  If ${{s}_{0}},{{s}_{1}},{{s}_{2}}$ and ${{s}_{3}}$. are the solubility's of $AgCl$ in water, $0.01M\,CaC{{l}_{2}},\,\,0.01\,M\,\,NaCl$ and $0.05\,M\,\,AgN{{O}_{3}}$ solutions, respectively, then 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)  ${{s}_{0}}>{{s}_{1}}={{s}_{2}}>{{s}_{3}}$

${{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 ${{s}_{0}}>{{s}_{2}}>{{s}_{1}}>{{s}_{3}}$
