A white sodium salt dissolves 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 dilute `HNO_(3)`.The anion is

Options

A. `CO_(3)^(2-)`
B. `Cl^(-)`
C. `SO_(3)^(2-)`
D. `S^(2-)`

Answer

B

Explanation

`NaCl+AgNO_(3)toAgCl darr("white")+NaNO_(3),Ag_(2)S darr` (black)
`Ag_(2)CO_(3)` and `Ag_(2)SO_(3)` dissolves in dilute `HNO_(3)` liberating `CO_(2)` and `SO_(2)` respectively.
Both `Ag_(2)CO_(3)` and `Ag_(2)SO_(3)` are white.`AgCl` is white but insoluble in dilute `HNO_(3)``NaCl` solution is netural to litmus as it is a salt of strong acid and strong base.
