Question

Solve this:

Q. In the complex ion [Fe(EDTA)]– the coordination number and oxidation state of central metal ion is :-

(1) C.N = 6 O.N = + 3

(2) C.N. = 1 O.N. = – 1

(3) C. N. = 4 O.N. = + 2

​ (4) C.N. = 3 O.N. = + 3

Answer 1

answer 1 is correct I hope it will help u

Answer 2

Explanation:

commonly C.N of Fe is 6

charge on EDTA is -4

ON solving for O.S of Fe we get +3
