Question

what is the oxidation number of Fe in Na2[Fe(CN)6]?​

Answer 1

Answer:

This is a neutral compound

So overall when u sum up all the oxidation no. of each element it should sum up to zero.

If u take those two Na atoms and rewrite it as [Fe(CN)6] ^-2

Cynaid group has oxidation no. as -1

Let oxidation no. of Fe be x

So 6(-1)+x=-2

Therefore x=4
