    A white sodium salt dissolves readily in water to give a solution which is neutral to litmus. When silver nitrate solution is added to the solution, a white precipitate is obtained which does not dissolve in dil. \[HN{{O}_{3}}.\]The anion could be

    A)  \[CO_{3}^{2-}\]                 

    B)  \[C{{l}^{-}}\]

    C)  \[SO_{4}^{2-}\]                             

    D)  \[{{S}^{2-}}\]

    Correct Answer: B

    Solution :

     NaCI is a salt of strong acid and strong base hence on dissolution will give neutral solution. \[NaCl+AgN{{O}_{3}}\to AgCl\downarrow +HN{{O}_{3}}\]
