For K3[Fe(CN)6] give the oxidation state of the transition metal followed by the coordination number?

Question

For the coordination compound K3[Fe(CN)6] give the oxidation state of the transition metal followed by the the coordination number.


Give two answers here with ONE and ONLY ONE between your two answers.A correct answer format would have the form, for example,+4 8Note the positive or negative sign precedes the number in the oxidation state.

Answer 1

Fe is the transitional metal

K3[Fe(CN)6] , we know that Potassium, K, has an oxidation number of +1, and therefore Fe(CN)6] must have an oxidation number of (-1*3)= -3

Fe(CN)6 = -3

The oxidation number of CN= -1, so 6*CN has an oxidation number of -6 so therefore

Fe - 6 = -3

Fe = -3 + 6 = +3

The oxidation number of Fe is +3.

In chemistry, the coordination number (c.n.), as defined originally in 1893 by Alfred Werner, is the sum of the total number of neighbors of a central atom in a chemical compound and the number of lone pairs on it. In this case Iron has 6 CN molecules attached to it and therefore the co-ordination number is 6.

Answer 2

Ox st = +3
Coord no = 6
