When `H_(2)S` gas is passed through a hot acidic aqueous solution containing `Al^(3+),Cu^(2+),Pb^(2+) and Ni^(2+)`, a precipitate is formed which consists of

A

Cus and `Al_(2)S_(3)`

B

PbS and NiS

C

CuS and NiS

D

PbS and Cus

Text Solution

Verified by Experts

The correct Answer is:
D
`H_(2)S` gas is passed through a hot acidic aqueous solution containing `Al^(3+),Cu^(2+),Pb^(2+) and Ni^(2+)`
II group elements give ppt `to` CuS, PbS

`Pb^(+2)Cu^(+2)Cd^(+2)Bi^(+2)Hg^(+2)" "As^(+3)Sb^(+3)Sn^(+2)Sn^(+4)`
