What are the oxidation states of iron in Fe2O3 and Fe3O4?

Question

Question

Answer 1

Answer #1

in fe2o3 in general oxygen shows the -2 so 3 oxygens shows the 3*-2 = -6

then for 2 Fe shows the +6

then for 1 Fe it shows the 6 / 2 = +3

in fe3o4 the 4 oxygens so 4*-2 = -8

the 3 Fe shows the +8 for the 1 Fe 8/3 = +2.67

answers = in fe2o3 fe = +3

= in fe3o4 fe = +2.67
