Question
Na2S + Na2[Fe(CN)5NO] → Na4[Fe(CN)5NOS] ; oxidation number of Fe in reactant (complex) and product (complex) are :
Options
A.2, 1
B.2, 2
C.2, 3
D.3, 3
Solution
[Fe(CN)5NO+]2- ; x + 5 (-1) + 1 = - 2 or x = +2
[Fe(CN)5NOS]4- ; x + 5 (-1) + (- 1) = - 4 or x = +2
[Fe(CN)5NOS]4- ; x + 5 (-1) + (- 1) = - 4 or x = +2
