What is the n factor for CO₂

ashishnavalakha

tell me its going to which o.s.
if its reduced to C₂O_{4^{--2,
then its nfactor of CO2 : 1
and nfactor of oxalate is : 2}}

sboosy

yes i think firstly the product shud be mentioned

bcos n factor may vary depending on that

anyway i think the author meant the oxalate reaction

the reaction is

C₂O₄^2--------> 2CO₂ + 2e^-

as per the reaction

per mole of C₂O₄^2-2 electrons transferred so n factor = 2

similarly for CO₂ it is 1

rockey

n-factor of co2 is one

svj29

the n-factor will depend on the reaction:

the basic an simple formula for calculating the n-factor is just calculate the change in OXIDATION STATE IN THE REACTION.
and u'l get the n-factor.
and ya as for the above answer itz not always necessary that CO2 will always reduce to form an oxalate ion.
