$(NH_{4})_{2} MoO_{4}$ and $HNO_{3}$ solution is used to detect $____$ due to the formation of yellow ppt.

Answer:

B, C

Solution:

(NH₄)₂MoO₄ in the presence of HNO₃ forms a yellow precipitate of ammonium phosphomolybdate.

This test is used to detect phosphate (PO₄³⁻) ions.

Similarly, arsenate (AsO₄³⁻) also gives a yellow precipitate with ammonium molybdate under acidic conditions.

Chloride and nitrate ions do not give this test.

Correct answer: (B) and (C)
