H2 S in the presence of HCl precipitate ...

`H_2 S` in the presence of HCl precipitate group II but not group IV because

A

HCl activates `H_(2)S`

B

HCl incraeses the concentration of `Cl^(-)`

C

HCl decreases the concentration of `S^(2-)` ions

D

HCl lowers the solubility of `H_(2)S` in the solution

Text Solution

Verified by Experts

Due to common ion effect, HCl suppresses the ionisation of `H_(2)S` thus decreasing the concentration of `S^(2-)` ions. Only group II radicals are precipitated.
