0.12 gm of an organic compound containing phosphorus gave 0.22 gm of `Mg_2P_2O_7` by the usual analysis. Calculate the percentage of phosphorus in the compound.

A

31

B

0.2

C

66

D

62

Text Solution

Verified by Experts

The correct Answer is:
D
The percentage of P present in the organic compound is given by ltnrgt `%` of `P=(62)/(222)xx("Weight of "Mg_(2)P_(2)O_(7))/("Weight of organic compound")xx100`
`=(62)/(222)xx(0.222)/(0.1)xx100=62`

Estimation of phosphorous: Second method: A known mass of compound is heated with fuming HNO_(3) or sodium peroxide (Na_(2)O_(2) in Carius tube which converts phosphorous to H_(3)PO_(4) . Magnesia mixture (MgCl_(2)+NH_(4)Cl) is then added, which gives the percipate of magnesium ammonium phosphate (MgNH_(4).PO_(4)) which on heating gives magnesium pyrophosphate (Mg_(2)P_(2)O_(7)) , which is weighted. Percentage of P =("Atomic mass of P")/("Molecular mass of " Mg_(2)P_(2)O_(7)) xx ("Molecular mass of "Mg_(2)P_(2)O_(7) xx 100)/("Mass of compound")=(62)/(222) xx("Mass of " Mg_(2)P_(2)O_(7)xx 100)/("Mass of compound") 0.12 gm of and organic compound containing phosphorus gave 0.22 gm of Mg_(2)P_(2)O_(7) by the usual analysis.
