In qualitative test for identification of presence of phosphorous, the compound is heated with an oxidizing agent. Which is further treated with nitric acid and ammonium molybdate respectively. The yellow coloured precipitate obtained is: (Jee Main 2024)
- \(\mathrm{Na}_{3} \mathrm{PO}_{4} \cdot 12 \mathrm{MoO}_{3}\)
- \(\left(\mathrm{NH}_{4}\right)_{3} \mathrm{PO}_{4} .12 \mathrm{MoO}_{3}\)
- \(\mathrm{MoO}_{4}\).\(21 \mathrm{NH}_{4} \mathrm{NO}_{3}\)
- \(\left(\mathrm{NH}_{4}\right)_{3} \mathrm{PO}_{4} \cdot 12\left(\mathrm{NH}_{4}\right)_{2} \mathrm{MoO}_{4}\)
Answer
(B) ( NH _ 4 )_ 3 PO _ 4 .12 MoO _ 3
