Question

What is the oxidation number of fe in K3[Fe(CN)6]

Answer 1

hope it's helpful.......

Answer 2

Answer:

k=1  CN=-1 then 1 x 3 + Fe + 6 x -1=0

3 + Fe + -6 =0

Fe=-3

Explanation:so the charge of k is 1 and the charge of CN is -1 and thus from the formula we have K3 then multiply it by its charge which is 1 and then for CN we have (CN)6 then you multiply it by its charge which is -1 and then add them to get the coordination number of Fe
