Question

If g is the mass of NaHC2O4 required to neutralize 100 mL of 0.2 MNaOH and y g that required to reduce 100 mL of 0.02 KMnO4 in acidic medium, then

Solution

Correct option is

 

Eq. mass of NaHC2O4 as an acid

Equiv. of  NaHC2O4 = Equiv of  NaOH

Eq. mass of NaHC2O4 as reductant

Equiv. of NaHC2O4 as reductant = Equiv. of KMnO4
