How oxidation possible at first? It is in maximum oxidation state.
And yes how are we supposed to answer this in exam as this is a JEE Question! Jd lee reading?

#3

I think they are talking about oxidation of impurities.
Besides Steel Making isn't in syllabus right?

#4

Bro I don't know whether IIT sticks to syllabus or not? Is it :100:% no question asked out of syllabus?
BTW.. @Ayan_Agrawal why would they mention steel making in syllabus, rather they assume this to be obvious part of d-block I think!

#5

Idk but I think they won't ask from it since it's not given in NCERT as well

But don't you think it is obvious that we usually consider the main metal and not the impurities ? @Ayan_Agrawal


I had this in my notes
Even I would have marked C .
Pls confirm @Supreeta_Sen @Viraam_Rao

Yup I said maybe impurities because oxidation of haematite ore doesn't make sense.
Never studied steel making so I have no idea what's going on.

First C gets oxidised to CO2 and CO then Fe2O3 gets reduced to Fe
I think that is what they mean
