To an aqueous solution containing ions such as
`Al ^(3+), Zn ^(2+) , Ca ^(2+), Fe ^(3+), Ni ^(2+), Ba ^(2+) and Cu ^(2+)` was added conc. HCl, followed by `H _(2) S.`
The total number of cations precipitated during this reaction is/are:

A

2

B

1

C

3

D

4

Text Solution

Verified by Experts

The correct Answer is:
B
Only group I and group II cations will get precipitated.
`therefore ` Only `Cu^(2+)` gets precipitated here.
