Are flame tests useful in determining identities of metals …
17/12/2017· Yes and no. A flame test will only really show the brighter or more visible flame of a given metal ion when one or more metal ions are present. For example, Sodium burns with a strong orange flame whereas potassium burns with a delie lilac based flame. If you have a mixture that contains both of these ions, the likelihood is that you would only really observe the stronger orange flame and

Colours of Transition Metal Ions in Aqueous Solution – …
Transition metal complexes are formed when transition metals are bonded to one or more neutral or negatively charged non-metal species, referred to as ‘ligands’. Without these bonds, all the d orbitals are equal in energy – however, once they are present, some d orbitals move to a higher energy than they were at before, whilst some move to a lower energy, creating an energy gap.
