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. `HNO_(3)`. The anion could be `:`A. `CO_(3)^(2-)`B. `Cl^(-)`C. `SO_(3)^(2-)`D. `S^(2-)` |

Answer» Correct Answer - 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. |
