    Ok, so I am posed the following statement and am asked to give the oxidation states:



    A = [Fe(H2O)6]2- - Oxidation state of Fe is in +2

    B = [Fe(CN)6]2- - Oxidation state is 0

    C = Ignore as complex isn't important in this case. Oxidation state is +3

    D = Fe(SCN)- - Oxidation state is +1

    Are the complexes and oxixdation states

    Also, what do the colours in the statement tell you about the complex?

    Thanks

    You cannot give an oxidation state to the entire ion or compound. You must assign an oxidation state to the iron atom (ion) only.

    Example:

    The oxidation state of the iron in the thiocyanate complex is +3
