A white sodium salt dissolves in water t...

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

A

`CO_(3)^(2-)`

B

`Cl^(-)`

C

`SO_(3)^(2-)`

D

`S^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
B
`NaCl+AgNO_(3) to AgCl 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 neutral to litmus as it is a salt of strong acid and strong base.
