The following can be used to regulate the concentration of `OH^(-)` ions for the scheme of basic radical analysis (`III` group)

A

`NH_(4)NO_(3)`

B

`NH_(4)Cl`

C

`(NH_(4))_(2)SO_(4)`

D

`(NH_(4))_(2)CO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A,B
`(NH_(4))_(2) CO_(3)` and `(NH_(4))_(2) SO_(4)` can not be used as they would also precipitate the `IV` and `V^(th)` group cations.
