A sodium salt solution (neutral) gives a yellow precipitate with $AgNO X_{3}$ that dissolves in both dilute $HNO X_{3}$ and aqueous $NH X_{3}$ . Which of the following observations will also be obtained with this solution? One or more options may be correct.

AA white precipitate with $BaCl X_{2}$ that is insoluble in dilute HCl.
BNo precipitate with $BaCl X_{2}$ in the presence of dilute HCl.
CA canary-yellow precipitate with ammonium molybdate and concentrated $HNO X_{3}$ on warming.
DA white crystalline precipitate with magnesia mixture.

A yellow silver precipitate soluble in both dilute

HNO X_{3}

and

NH X_{3}

Ag X_{3} PO X_{4}

(

AgI

and

AgBr

do not dissolve in

HNO X_{3}

), so the anion is phosphate. It therefore gives the yellow phosphomolybdate and white

MgNH X_{4} PO X_{4}

. Barium phosphate dissolves in dilute HCl, so no sulphate-type precipitate forms. Correct: first, second and third.
