Which of the following halides react(s) with `AgNO_(3(aq))` to give a precipitate that dissolves in `Na_(2)S_(2)O_(3(aq))`A. `HCI`B. `HF`C. `HBr`D. `HI`

Answer» Correct Answer - A::C::D
`AgNO_(3)+HCI rarr AgCI darr`
`AgNO_(3)+HBr rarr AgBr darr`
`AgNO_(3)+HI rarr AgI darr`
All these precipitates will get dissolved in hypo `(Na_(2)S_(2)O_(3))` formaing complex, `Na_(3)[Ag(S_(2)O_(3))_(2)]`
