In an organic compound phosphorus is estimated as
- A \(\mathrm{Mg}_3\left(\mathrm{PO}_4\right)_2\)
- B \(\mathrm{P}_2 \mathrm{O}_5\)
- C \(\mathrm{Mg}_2 \mathrm{P}_2 \mathrm{O}_7\)
- D \(\mathrm{H}_3 \mathrm{PO}_4\)
Answer & Solution
Correct Answer
(C) \(\mathrm{Mg}_2 \mathrm{P}_2 \mathrm{O}_7\)
Step-by-step Solution
Detailed explanation
In organic compound, phosphorus can be estimate by precipitating it as \(\mathrm{MgNH}_4 \mathrm{PO}_4\), by adding magnesia mixture. On ignition of precipitate, it yields \(\mathrm{Mg}_2 \mathrm{P}_2 \mathrm{O}_7\).
