Aqueous solution of a salt when treated with `AgNO_(3)` solution gives a white precipitate , white dissolves in `NH_(4)OH`. Radical present in the salt isA. `Cl^(-)`B. `S^(2-)`C. `I^(-)`D. All of them |

Answer» Correct Answer - A When `Cl^(-)` is treated with `AgNO_(3)` solution in presence of dilute `HNO_(3)`, corresponding silver halide is obtained which is soluble in `NH_(4)OH, NaCN,` and `Na_(2)S_(2)O_(3)`. `AgNO_(3)+NaClrarr AgClunderset("white")(+)NaNO_(3)` `AgCl+"dil. " 2NH_(4)OH underset("complex")([Ag(NH_(3))_(2)Cl)+ 2H_(2)O` |
