Question

Yellow precipitate in phosphorus detection (after Na fusion, HNO₃, and ammonium molybdate) is due to formation of ______.

विकल्प

• (NH₄)₃.PO₄.12MoO₃

• (MH₄)₃.PO₄.6MoO₃

• (NH₄)₃.PO₄.12MoO₂

• (NH₄)₃.PO₄.6MoO₂

Answer 1

Yellow precipitate in phosphorus detection (after Na fusion, HNO₃, and ammonium molybdate) is due to formation of (NH₄)₃.PO₄.12MoO₃.

Explanation: 

Yellow precipitate in the detection of phosphorous when an organic compound is heated with Na₂0₂ and then boiled with conc. HNO₃ followed by the addition of ammonium molybdate is due to formation of (NH₄)₃.PO₄.12MоO₃.
