Question

Calculate the oxidation number of Fe in Fe4[Fe(CN)6]3

Answer 1

There is some mistake in this compound as we know that the oxidation no. of all elements should be zero So if Fe has +4 oxidation no. then bracket will has -4 oxidation then +4-4=0 .whole bracket has -4 oxidation no. so sum of oxidation no. of CN nd Fe must be -4 As CN has -6 oxidation no. then Fe must has +2 oxidation no. bcz -6+2=-4
