Answer» Aqueous solution of 'A' on treatment with `AgNO_(3)` gives 'B' white ppt. of `Ag_(2)S_(2)O_(3)` Aqueous solution of 'A' on treatment with `AgNO_(3)` gives white ppt. of `Ag_(2)SO_(3)`. Compound 'C' is `Ag_(2)S`, which is black in COLOUR The violet colouration of compound (E) is `[FE(S_(2)O_(3))_(2)]^(-)`, which turns into `FeS_(4)O_(6)`. ANSWER :A::C::D
