When a KI solution is added to a metal nitrate, a black precipitate is produced which dissolves in an excess of KI to give an organge solution. The metal ion is:

A

`Hg^(2+)`

B

`Bi^(3+)`

C

`Cu^(2+)`

D

`Pb^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
B
`Bi^(3+)+3I^(-) to underset(("black"))(BiI_(3))overset(I^(-))to underset(("orange soluble"))([BiI_(4)]^(-))`
