D

`[Ag(SO_(3))_(3)]^(3-),Ag_(2)SO_(4),Ag`

Text Solution

Verified by Experts

The correct Answer is:
A
`Ag^(+)+underset("(clear Solution)")underset("X ")(2S_(2)O_(3)^(2-)rarr)underset(" (white)")underset(" Y")([Ag(S_(2)O_(3))_(2)]^(3-))overset(Ag^(+))rarrunderset(" (black)")(underset(" z")(Ag_(2)S_(2)O_(3)))overset("with time")rarrAg_(2)S`
`Ag_(2)S_(2)O_(3)+H_(2)OrarrAg_(2)S+H_(2)SO_(4)`
