Which of the following salts will not produce any observable changes when `H_(2)S` is passed through its aqueous solution?

A

`(CH_(3)CO_(2))Pb`

B

`Na_(2)[Ge(CN)_(5)NO]`

C

`AgNO_(3)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`H_(2)S` is a weak acid, so does not dissociate significantly to gives `S^(2-)`. Alkaline medium helps.
