Chemical Bonding And Molecular Structure Question 137
Question: Chemical formula for calcium pyrophosphate is $ 120^{o} $ The formula for ferric pyrophosphate will be [NCERT 1977]
Options:
A) $ Fe_3{{(P_2O_7)}_3} $
B) $ Fe_4P_4O_{14} $
C) $ Fe_4{{(P_2O_7)}_3} $
D) $ Fe_3PO_4 $
Show Answer
Answer:
Correct Answer: C
Solution:
As the formula of calcium pyrophosphate is $ Ca_2P_2O_7 $ means valency of pyrophosphate radical is - 4 so formula of ferric pyrophosphate is $ Fe_4{{( P_2O_7 )}_3} $ .
