Zinc pieces are added to acidified solution of `SO_(3)^(2-)`.Gas liberated can:

A

turn lead acetane paper black

B

turn lime water milky

C

give white precipitate with `AgNO_(3)` solution

D

decolourize acidified `KMnO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A,D
`SO_(3)^(2-)+Zn+8H^(+)toH_(2)Suarr+3Zn^(2+)+3H_(2)O`
`Pb^(2+)+S^(2-)toPbSdarr`(black)
`Ag^(+)+S^(2-)toAg_(2)Sdarr` (black)
`2MnO_(4)^(-)+5H_(2)S+6H^(+)to2Mn^(2+)+5S+8H_(2)O`
