turn lead acetate paper black

B

turn lime water milky

C

give white precipitate with `AgNO_(3)` solution

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A

`SO_(3)^(2-)+Zn +8H^(+) to H_(2)S uarr + 3Zn^(2+)+3H_(2)O`
`Pb^(2+)+S^(2-) to PbS darr ("black")`
`Ag^(+)+S^(2-) to Ag_(2)S darr ("black")`
