Which of the following reagents can be used for making the distinction between `AgCl` and `Agl`?

Options

A. Sodium arsenite solution
B. Dilute ammonia solution
C. Potassium cyanide solution
D. Dilute `HNO_(3)`

Answer

A,B

Explanation

(A)`3AgCldarr+AsO_(3)^(3-)toAg_(3)AsO_(3)darr ("yellow")+3Cl^(-)`
`Agl` is unaffected by this treatment.
(B)`AgCl+2NH_(3)to[Ag(NH_(3))_(2)]Cl`
`Agl` is not soluble in dilute ammonia solution.
( C)Both soluble in potassium cyanide, forming soluble complexes.
(D)Both insoluble in dilute `HNO_(3)`
