VA group precipitate was dissolved in HN...

`VA` group precipitate was dissolved in `HNO_(3)` and treated with excess of `NCl_(5)`. It gives a white ppt. because of

A

`Cu(OH)_(2)`

B

`Cd(OH)_(2)`

C

`Bi(OH)_(3)`

D

`Hg(OH)_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
When the black `ppt` of `CS_(2)` is dissolved in `50%HNO_(3)` and a solution of `NH_(4)OH` is added. A white `ppt.` of `Bi(OH)_(3)` is obtained.
