  • question_answer
    The solubiulity of\[AgCl\]is\[1.8\times {{10}^{-3}}\]g/L at\[25{}^\circ C\]The solubility product of\[AgCl\]will (Ag = 108, \[Cl=35.5\])

    A)  \[1.57\times {{10}^{-10}}\]     

    B)  \[1\times {{10}^{-10}}\]

    C)  \[3.24\times {{10}^{-6}}\]      

    D)  \[1\times {{10}^{-6}}\]

    Correct Answer: A

    Solution :

     Solubility of\[AgCl=1.8\times {{10}^{-3}}g/L\] \[=\frac{1.8\times {{10}^{-3}}}{143.5}mol/L\] \[=1.25\times {{10}^{-5}}mol/L\] Solubility product of \[AgCl={{(solubility)}^{2}}\] \[={{(1.25\times {{10}^{-5}})}^{2}}\] \[=1.57\times {{10}^{-10}}\]
