1.	What is the primary valence of iron in the coordination entity of compound Fe4[Fe(CN)6]3?(a) 0(b) +2(c) +3(d) +4The question was asked during an interview.My query is from Werner’s Theory of Coordination Compounds topic in section Coordination Compounds of Chemistry – Class 12
Answer» Correct answer is (b) +2 For EXPLANATION: This COMPOUND, also known as PRUSSIAN blue, dissociates into 4 Fe^3+ and 3[Fe(CN)6]^4- ions, of which the latter is the coordination entity having a CHARGE of -4. The Fe atom in question is the one inside the bracket. Since CN has a charge of -1 and there are 6 of them, the primary valence of Fe will be 6 – 4 = +2.
