Question

How will you test for phosphorus in any organic compound?

✓

Answer

When organic compound is heated with sodium peroxide (oxidant), then the phosphorus present in compound, convert to phosphate. Then the solution is boiled in $HNO _3$, ammonium molybdate solution is added from which yellow solution or precipitate is obtained, which confirms the presence of phosphorus.
