Question

what is the n-factor of iron oxalate? FeC2O4

Answer 1

Answer:

So, the oxidation number of carbon changes from +3 to +4. As, there are two carbon atoms, the net change in oxidation number is +2 and adding to this the increase in oxidation state of iron, the final increase in oxidation number is +3. Hence, the n-factor of is 3.
