Test tube of copper/1,2 diaminoethane (ethylenediamine) complex ion. The ions of transition metals are coloured and this makes it possible to tell which ion is present in a solution. The copper/1,2 diaminoethane complex ion is purple because most of the absorption band is in the green part of the spectrum - 530nm | |
