Colour changes due to ligand exchange. Samples of solutions containing various complex ions of nickel,showing the effect of ligand exchange on colour. At left (green) is a solution containing the hexaaquanickel(II) ion; six water molecules surrounding a nickel atom. In the next solution (pale blue),each complex ion has had two water molecules replaced by a single 1,2-diaminoethane molecule. Right of centre (dark blue),a further two water molecules have been replaced. At right (purple),the complex now consists of three 1,2- diaminoethane molecules and no water around each nickel atom | |
