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) 3AgCl darr + AsO_(3)^(3-) to Ag_(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)`.
