Question

# The number of moles of $$KMnO_4$$ that will be needed to react completely with one mole of ferrous oxalate in acidic medium is:

A
25
B
35
C
45
D
1

Solution

## The correct option is C $$\dfrac {3}{5}$$The balanced chemical reaction is as shown below:$$3MnO_4^-+5FeC_2O_4+24H^+\rightarrow 3Mn^{2+}+5Fe^{3+}+10CO_2+12H_2O$$$$3$$ moles of $$KMnO_4$$ react with $$5$$ moles of $$FeC_2O_4$$.Hence, the number of moles of $$KMnO_4$$ that will be needed to react completely with one mole of ferrous oxalate in acidic medium is $$\dfrac {3}{5}$$.Hence, the correct option is $$B$$Chemistry
