Magnesium pyrophosphate ($Mg_{2}P_{2}O_{7}$,$222 \ g/mol$) and Ammonium phosphomolybdate ($(NH_{4})_{3}PO_{4} \cdot 12MoO_{3}$,$1877 \ g/mol$)

Vedclass · Answer

(A) In the estimation of phosphorus,the organic compound is heated with fuming nitric acid,which converts phosphorus into phosphoric acid. $1$. Phosphoric acid is precipitated as ammonium phosphomolybdate by adding ammonia and ammonium molybdate. The formula is $(NH_{4})_{3}PO_{4} \cdot 12MoO_{3}$ and its molecular mass is $1877 \ g/mol$. $2$. Alternatively,it can be precipitated as magnesium ammonium phosphate,which on ignition gives magnesium pyrophosphate. The formula is $Mg_{2}P_{2}O_{7}$ and its molecular mass is $222 \ g/mol$.
