in case both S and N are present, sodium thiocyanate is formed which is Blood red in colour. Na+C+N+S ---> NaSCN Fe^+3. + SCN^-1 ---> [Fe(SCN)]^+2

and if I react sodium thiocyanate with excess Na it decomposes to give Cyanide and Sulphide. NaSCN + 2Na ---> NaCN + Na2S
I have already studied this chapter. Value of x is 5.;-)
Ferriferrocyanide and Iupac Iron(III) hexacyanoferrate(II)
x is 5 and the compound is ferriferrocyanide.
