Consider solutions of the following complex ions. which solutions would be expected to be colorless and which would exhibit color?

complex ions that would be colorless include

(i) scandium iii

(ii) zinc ii

Complex ions with color include

Copper ii

Iron ii

Iron iii etc

Explanation:

Scandium iii and zinc ii are colorless complexes because its 3d level is empty the are sometimes not regarded as a transition element. WHILE

Complex ions containing transition metals are usually coloured this is because of the partly field orbitals which is involved in generating the color in some ways.
