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

Answer»

`CO_(3)^(2-)`
`Cl^(-)`
`SO_(3)^(2-)`
`S^(2-)`

Solution :`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` solutionisnetural to litmus as it is a salt of strong acid andstrongbase.
